title: ExtJS multiple listeners
body: <p>I have a property grid that I want to add multiple "afterrender" listeners to. Is it possible to add multiple listeners of the same type, or fire multiple functions within one listener?</p>
  
  <p>I've tried:</p>
  
  <pre><code>afterrender: function(){...},
  function(){...}
  </code></pre>
  
  <p>but it does not fire both of the functions.</p>
