title: <input type="file"> is undefined after simple file select
body: <p>I have:</p>
  
  <pre><code>&lt;input type="file" name="fileToUpload" id="fileToUpload" /&gt;
  </code></pre>
  
  <p>Clicking the "Choose file" button allows me to select a file using Finder/Explorer/whatever. When I click "Open" and return to my form, the text "No file chosen" remains.</p>
  
  <p>If i check the value using:</p>
  
  <pre><code>$("#fileToUpload").change(function() {
          console.log($("#fileToUpload").value);
      });
  </code></pre>
  
  <p>The value is undefined. I am tearing my hair out because this is so, so simple and it's not working. What can I be missing?</p>
