Retrieving data from a form loaded with jQuery and passing it to a parent page

I have a 'parent' page that is using the following bit of code to pull in a form from a different page on the same domain. There are reasons why I can't just place the form directly on the 'parent'.

<script type="text/javascript">jQuery("#ai_temp_profile_edit").load("http://ift.tt/1JRbRpV #profile-edit-form" , function() { }).hide().fadeIn(1000);</script>

The form that is pulled in looks like this:

<form action="http://ift.tt/1JRbRpV" method="post" id="profile-edit-form" class="standard-form base" target="hiddenFrame">
    <label for="field_1">Name</label>
    <input  id="field_1" name="field_1" type="text" value="Joey-Jojo Jr. Shabadoo">
    <input type="submit" name="profile-group-edit-submit" id="profile-group-edit-submit" value="Save Changes " />
    <input type="hidden" name="field_ids" id="field_ids" value="1" />
    <input type="hidden" id="_wpnonce" name="_wpnonce" value="a62f8d5fec" />
    <input type="hidden" name="_wp_http_referer" value="/form/" />
</form>

When 'submit' is clicked, http://ift.tt/1JRbRpV is opened in a hidden iframe and the user name gets properly saved. This all works well.

I would like the user name on the currently loaded 'parent' page to update via jquery, so that the user has some immediate visual feedback that the name change has taken place.

My approach has been to try and take the value out of the 'field_1' input when 'submit' has been clicked, and pass that variable onto a in the parent page with an id of 'display_name'.

$(document).ready(function(){
function nameUpdate(){
    $("#profile-group-edit-submit").click(function () {
    var updateName = $("#field_1").val();
    $("#display_name").text(updateName);
    });
}       
nameUpdate();

});

I've also tried adding

window.parent.

before the the #display_name selector section and it didn't change anything.

I've used this approach on another button/div combo on the same page and it works, the difference is that that particular button is in an iframe, not loaded by jquery. So I'm guessing my problem is related to that fact.

I've googled around, but have run out of ideas of how to phrase my question, what to look for, etc...

Any help would be greatly appreciated. Thanks!
