[TIMOB-5766] iOS: tabbedBar doesn't consistently fire click events

var win = {};

// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');

var rootWin = Titanium.UI.createWindow({
  
});


win.main = Titanium.UI.createWindow({  
});
win.rootNav = Titanium.UI.iPhone.createNavigationGroup({
   window: win.main
});
rootWin.add(win.rootNav);
rootWin.open();

function showWin(){
  var newWin = Titanium.UI.createWindow({
  });  

  var tb2 = Titanium.UI.createTabbedBar({
    labels:[
      {title: 'A', width: 100, enabled:true},
      {title: 'B', width: 100, enabled:true},
      {title: 'C', width: 100, enabled:true}  
    ],
  });
  tb2.addEventListener('click', function(e){
    alert('I work!');

  });
  
  newWin.setToolbar([tb2]);    

  win.rootNav.open(newWin);

}

showWin();
