title: document.getElementById().value doesn't set the value
body: <p>Browser is chromium (under ubuntu)</p>
  
  <p>This is a chunk of code: (of course) The alert messages shows the right value. but the points 
  element doesn't get the right value, it actually gets empty. Can anybody tell me why? </p>
  
  <p>Here's how points element is defined.</p>
  
  <pre><code>&lt;input type='number' id='points' value='0'/&gt; 
  </code></pre>
  
  <p>and here is how javascript code is supposed to populate it.</p>
  
  <pre><code>alert(request.responseText);
  
  document.getElementById("points").value=request.responseText;
  </code></pre>
