Use http cookie value in an Angular template

I have angular working in one of my ASP.NET MVC applications. I am using two html templates with Angular Routing. One is a list of current Favorites that comes from the database and is serialized into json from my Web API and used by angular to list those items from the database.

The second html template is a form that will be used to add new favorites. When the overall page that includes my angular code loads, it has a cookie named currentSearch which is holding the value of whatever the last search parameters executed by the user.

I would like to inject this value into my angular html template (newFavoriteView.html) for the value of a hidden input named and id'd searchString.

I have tried using jQuery, but had problems, plus I would much rather do this inside of angular and somehow pass the value along to my template or do the work inside the view(template). However, I know the latter would be bad form. Below is the code I think is important for one to see in order to understand what I am doing.

Index.cshtml (My ASP.NET VIEW)

@{
    ViewBag.Title = "Render Search";
    ViewBag.InitModule = "renderIndex";
}
    <div class="medium-12 column">
        <div data-ng-view=""></div>
    </div>
@section ngScripts {
    <script src="~/ng-modules/render-index.js"></script>
}

Setting the cookie in the MVC Controller

    private void LastSearch()
    {
        string lastSearch = null;
        if (Request.Url != null)
        {
            var currentSearch = Request.Url.LocalPath + "?" + 
                                    Request.QueryString;

            if (Request.Cookies["currentSearch"] != null)
            {
                lastSearch = Request.Cookies["currentSearch"].Value;
                ViewBag.LastSearch = lastSearch;
            }

            if (lastSearch != currentSearch)
            {
                var current = new HttpCookie("currentSearch", currentSearch){ 
                                   Expires = DateTime.Now.AddDays(1) };
                Response.Cookies.Set(current);

                var previous = new HttpCookie("lastSearch", lastSearch) { 
                                   Expires = DateTime.Now.AddDays(1) };
                Response.Cookies.Set(previous);
            }
        }
    }

render-index.js

angular
    .module("renderIndex", ["ngRoute"])
    .config(config)
    .controller("favoritesController", favoritesController)
    .controller("newFavoriteController", newFavoriteController);

function config($routeProvider) {
    $routeProvider
        .when("/", {
            templateUrl: "/ng-templates/favoritesView.html",
            controller: "favoritesController",
            controllerAs: "vm"
        })
        .when("/newsearch", {
            templateUrl: "/ng-templates/newFavoriteView.html",
            controller: "newFavoriteController",
            controllerAs: "vm"
        })
        .otherwise({ redirectTo: "/" });
};

function favoritesController($http) {
    var vm = this;
    vm.searches = [];
    vm.isBusy = true;

    $http.get("/api/favorites")
        .success(function (result) {
            vm.searches = result;
        })
        .error(function () {
            alert('error/failed');
        })
        .then(function () {
            vm.isBusy = false;
        });
};

function newFavoriteController($http, $window) {
    var vm = this;
    vm.newFavorite = {};
    vm.save = function () {
        $http.post("/api/favorites", vm.newFavorite)
            .success(function (result) {
                var newFavorite = result.data;
                //TODO: merge with existing topics
                alert("Thanks for your post");
            })
            .error(function () {
                alert("Your broken, go fix yourself!");
            })
            .then(function () {
                $window.location = "#/";
            });
    };
};

favoritesView.html

<div class="container">
    <h3>New Favorite</h3>
    <form name="newFavoriteForm" ng-submit="vm.save()">
    <fieldset>
      <div class="row">
        <div class="medium-12 column">
          <input name="searchString" id="searchString" type="hidden" 
                 ng-model="vm.newFavorite.searchString"/>
            <label for="title">Name</label><br />
              <input name="title" type="text" 
                     ng-model="vm.newFavorite.name"/>
                <label for="title">Description</label><br />
                <textarea name="body" rows="5" cols="30" 
                          ng-model="vm.newTopic.description"></textarea>
              </div>
              <div class="medium-12 column">
                <input type="submit" class="tiny button radius" value="Save"/> | 
                <a href="/" class="tiny button radius">Cancel</a>
              </div>
          </div>
      </fieldset>
  </form>
</div>

My current attepts have been using jQuery at the end of the page after Angular has loaded and grab the cookie and stuff it in the hidden value. But I was not able to get that to work. I also thought about setting the value as a javascript variable (in my c# page) and then using that variable in angular some how. AM I going about this the right way?

Or should it be handled in the angular controller?...

I'm new to angular and the Angular Scope and a bit of ignorance are getting in the way. If any other info is needed I can make it available, thanks if you can help or guide me in the right direction.
