title: Items appended to listview are not clickable
body: <p>When I add content to my listview in jQuery Mobile, they don't trigger the click event when clicked. In my example below, 'Cadillac' is not clickable. Am I doing something wrong?</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div data-role="page" id="p1"&gt;
      &lt;ul data-role="listview" data-theme="b"&gt;
          &lt;li&gt;&lt;a href="#"&gt;Acura&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Audi&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;BMW&lt;/a&gt;&lt;/li&gt;
      &lt;/ul&gt;
  &lt;/div&gt; 
  </code></pre>
  
  <p>jQuery:</p>
  
  <pre><code>$('li').on('click',function(){
      alert('clicked');            
  });
  
  $('ul').append('&lt;li&gt;&lt;a href="#"&gt;Cadillac&lt;/a&gt;&lt;/li&gt;');
  $('ul').listview('refresh');
  </code></pre>
