"el" listener not working in Sencha Touch 2

I'm using Sencha Touch 2.0-pr3. I'm having trouble getting the element tap event to work (note that BrowsePage extends Ext.Panel). I'm confused cause this works in Sencha Touch 1. What's changed?!

var resultsPage = Ext.create('bla.myapp.BrowsePage', {
  id: 'searchResults',
  html: str,               
  listeners: {
    el: {
      tap: function() {
        console.log('hi!');
      }
    }
  }
})

Someone answered my questions here: http://www.sencha.com/forum/showthread.php?161806-%E2%80%9Cel%E2%80%9D-listener-not-working-in-Sencha-Touch-2&p=691670&viewfull=1#post691670

It's not in ST2 yet, so for now override initialize() --

initialize: function() {
    this.callParent();

    this.element.on({
    ...
    });
}
