title: jQuery 1.9 doesn't bubble file select/change event in old Firefox
body: <p>As of jQuery 1.9, the file select change event doesn't bubble / propagate anymore in old Firefox.  It was fine in jQuery 1.8, but it stopped working in jQuery 1.9.</p>
  
  <p>Here is an example:</p>
  
  <pre><code>&lt;ul class="result"&gt;&lt;/ul&gt;
  &lt;div class="wrapper"&gt;
      &lt;input class="file_input" name="file" type="file" /&gt;
  &lt;/div&gt;
  &lt;script&gt;
  $('.wrapper').on('change', '.file_input', function() {
      $('.result').append('&lt;li&gt;file selected&lt;/li&gt;');
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Here's a fiddle using jQuery 1.8 that demonstrates how I expect the behavior to work:</p>

  <p>In all browsers (including Firefox 3.6), every time I select a file, the change event on the input[type=file] element bubbles.</p>
  
  <p>Here's the same example using jQuery 1.9.  Using Firefox 3.6, the change event no longer bubbles.   It seems to work fine in Firefox 18+ though:</p>

  <p><strong>This leads me to 2 questions:</strong></p>
  
  <p>1) What version of Firefox does this stop working?</p>
  
  <p>2) Is there a way around this problem?</p>
