[TIMOB-14631] BlackBerry: Not able to get e.source on click event for UI controls such as window, view, button etc

Not getting e.source on click event for UI controls. Checked with view,button and window. This is not a regression. Steps to reproduce: 1) Make a test Project and replace app.js with the code given below. 2) Launch the app. 3) After the app gets launched. Click the button.

var win = Ti.UI.createWindow({backgroundColor:'white'});
  
var btn = Ti.UI.createButton({
    title: 'click me',
    height: 50,
    width: 150,
    color:'black'
});
 
btn.addEventListener('click',function(e){
    alert(JSON.stringify(e.source));
});
win.add(btn);
win.open();

Actual Result: Do not get anything it just returns empty JSON as"{}" Expected Result:It must return button properties as in ios and android.
