Problems with Container Event

I want to add a tap event to a Container.

The following solution works outside sencha architect:

HTML Code:

---

listeners: {
    tap: {
      element: 'element',   
      delegate: '#test',     
      fn: function(e) {         
            alert('Element with id "test" was tapped!');       
}   
} }

But I couldn't figure out how this works with Sencha Architect. If I open up the architect after adding the code it will erase my changes. Why?

How to add this in Sencha Architect?

set up a controller function for that panel and add the below

Code:

---

container.element.on('tap', function() {

}, container);
