title: <select> change event not fired when using keyboard
body: <p><a href="http://jsfiddle.net/rFEER/" rel="noreferrer">http://jsfiddle.net/rFEER/</a></p>
  
  <pre><code>&lt;select id="users"&gt;
  &lt;option value="1"&gt;jack&lt;/option&gt;
  &lt;option value="2"&gt;brill&lt;/option&gt;
  &lt;option value="3"&gt;antony&lt;/option&gt;
  &lt;/select&gt;​
  </code></pre>
  
  <p>js:</p>
  
  <pre><code>$("#users").change(function(){
      alert($(this).val());
  })​
  </code></pre>
  
  <p>why change event not fired when using (keyup/keydown) until mouse is clicked</p>
