MEAN.JS Contact Form

Trying to create a contact form and feedback form for my website. Here is my controller in angular that I'm using however I need to understand what's going on with my routes and how to implement this inside MEAN.JS please advice:

angular.module('core').controller('FormCtrl',['$scope','$http', function($scope,$http) {
    $scope.postMail = function (data) {
           $http.post('/mail', data).success(function(data, status, headers, config) {
             alert('success');
             //close function....??
           }).error(function(data, status, headers, config) {

        });
     };

 }]);//formController ends
