title: .ajaxStart and .ajaxStop not firing for some odd reason
body: <p>I append a "Loading" class to the body when an ajax request is made so i could then display a progress animation...
  For some reason the functions ae never called and I see no alerts...</p>
  
  <pre><code>function setLoadingPanel()
  {
      var timer;
      var body = $("body");
  
      alert("Set AJAX HOOKS...");
      $("body").on({
          ajaxStart: function ()
          {
              alert("AJAX START");
              //timer = setTimeout(function () { body.addClass("loading"); }, 50)
          },
          ajaxStop: function ()
          {
              alert("AJAX STOP!!!");
              //$(this).removeClass("loading");
              //clearTimeout(timer);
          }
      });
  }
  </code></pre>
  
  <p>I have placed alerts to try and see if the hooks are called but no alert is poping for some reason.</p>
  
  <p>Here is my ajax request using a simple AJAX.ActionLink helper:</p>
  
  <pre><code>@{
      var ajaxDialogoptions = new AjaxOptions()
      {
          HttpMethod = "GET",
          InsertionMode = InsertionMode.Replace,
          UpdateTargetId = "DialogContainer",
          OnComplete = "OpenDialog('DialogContainer');"
      };
  }
  @Ajax.ActionLink(Model.AddNewItemButtonTitle, Model.AddActionName, Model.AddActionController, Model.AddActionRoutValues, ajaxDialogoptions, new { Class = "btn btn-primary anti-align-rtl" })
  </code></pre>
  
  <p>Here is my Bundle of scripts:</p>
  
  <pre><code>            Bundle bundle = new Bundle("~/Scripts/jsRTL");
  
              bundle.AddFile("~/Scripts/Common/jquery-1.9.1.min.js");
