title: Firefox fail to trigger jQuery event
body: <p>Following code triggers an event when clicking an anchor.
  The event should be captured on the second function to launch an alert.
  The code succeeds on Google Chrome, but fails on Firefox 36.0.1
  Does anybody sees where is the problem?</p>
  
  <pre><code>&lt;a href='#'&gt;clic here&lt;/a&gt;
  &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script&gt;
      $(document).ready(function () {
  
          $(document).on('click', 'a', function (e) {
              event.preventDefault();
              $(document).trigger('RaiseHelloWorld', {});
          });
  
          $(document).on('RaiseHelloWorld', function (e, argument) {
              alert('Hello World!');
          });
       });
  &lt;/script&gt;
  </code></pre>
