Alphabetical order not working when loading external checkboxes

I'm pulling in some checkboxes from an external HTML file to a tab container, and after they load I want them sorted alphabetically. The sorting works fine when the checkboxes load internally, but when loaded externally the sorting fails. Don't know if this is a delay issue or other error. I've tried delay(), setTimeout(), and hints from related posts but nothing works. Any ideas anyone? Fiddle: http://ift.tt/2kdTw2s

<ul class="tabs-nav">
 <li class="tab-active"><a href="#Container" rel="nofollow">Countries</a></li>
 <li class=""><a href="#blank2" rel="nofollow">Year</a></li>
 <li class=""><a href="#blank3" rel="nofollow">Products</a></li>
</ul>

<div class="TabContainerClass">

<div id="Container">
<div id="CountryID" class="CountryClass">

<!--
<label class="myEuropeCountries"><input type="checkbox"  id="UN400" value="Poland" />Poland</label>
<label class="myEuropeCountries"><input type="checkbox"  id="UN500" value="Macedonia" />Macedonia</label>

// Loading from external file & sorting alphabetically

$(function() {
  $.get('http://ift.tt/2ke08xG', function(data) {
var $data = $(data);
$("#CountryID").html($data.find('#CountryStore_ws'));
  });

  function sortByText(a, b) {
    return $.trim($(a).text()) > $.trim($(b).text()) ? 1 : -1;
  }

  var li = $(".CountryClass").children("label").detach().sort(sortByText);
  $(".CountryClass").append(li)
