title: keydown event is not working for input type search in jquery mobile
body: <p>I want to invoke keydown event for input type search in jquery mobile. Below is my html code.</p>
  
  <pre><code> &lt;!DOCTYPE html&gt;
  &lt;html&gt;
   &lt;head&gt;
      &lt;meta charset="ISO-8859-1"&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
      &lt;title&gt;Insert title here&lt;/title&gt;
  &lt;link rel="stylesheet" href="jquery.mobile-1.2.0.min.css"&gt;
  &lt;script type="text/javascript" src="jquery.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript"&gt;
  $(document).ready(function() {      
      $("#search1").keydown(function() {
          alert("keydown");           
          $("#search1").css("background-color", "yellow");
      });
      $("#search1").keyup(function() {
          alert("keyup");
          $("#search1").css("background-color", "pink");
      });
  });
  &lt;/script&gt;
  &lt;script type="text/javascript" src="jquery.mobile-1.2.0.min.js"&gt;&lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div data-role="page"&gt;
  
  &lt;div data-role="content"&gt;
  &lt;input type="search" id="search1"&gt;
  &lt;input type="text" id="text1"&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>keydown event is getting fired for all the other input types, except for search type. Can someone please help on this?</p>
