[TIMOB-17466] [iOS] TabGroup Event : Problem with the refresh of Components after a focus of Tab

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

// create tab group
var tabGroup = Titanium.UI.createTabGroup({
	visible : false
});

tabGroup.addEventListener("focus" , function(e){
	
	if (view_test.opacity == 1 && tabGroup.visible) {
		view_test.top = Ti.Platform.displayCaps.platformHeight;
	}
	
});





var win1 = Titanium.UI.createWindow({  
    title:'Tab 1',
    backgroundColor:'#fff'
});
var tab1 = Titanium.UI.createTab({  
    icon:'KS_nav_views.png',
    title:'Tab 1',
    window:win1
});

var label1 = Titanium.UI.createLabel({
	color:'#999',
	text:'I am Window 1',
	font:{fontSize:20,fontFamily:'Helvetica Neue'},
	textAlign:'center',
	width:'auto'
});

win1.add(label1);

var view_test = Ti.UI.createView({
	width : 320,
	height : Ti.Platform.displayCaps.platformHeight,
	backgroundColor : "black",
	opacity : 1,
	top : Ti.Platform.displayCaps.platformHeight
});

var label_test = Ti.UI.createLabel({
	text : "Close",
	color : "white"
});
view_test.add(label_test);

	view_test.animate({

var win2 = Titanium.UI.createWindow({
