title: click event on new element after html update in Sencha touch
body: <p>I create a new element inside Ext.Panel by template</p>
  
  <p>i want to add an click event to p#more element</p>
  
  <p>if i put:</p>
  
  <pre><code>Ext.select('#more').on('click', function() {
   // my code
  });
  </code></pre>
  
  <p>inside <code>handler: function()</code>  of <code>Ext.Panel</code> it works</p>
  
  <p>but then i update the html inside the panel and event is not working anymore!!!</p>
  
  <p>is there an listener for newly created DOM elements I can put my click event inside?</p>
