[TIMOB-15412] Focus events stops working when you create and open a new window before opening of tabgroup

function ApplicationTabGroup(Window) {
	//create module instance
	var self = Ti.UI.createTabGroup();

	var topWindow = Ti.UI.createWindow({
		width : '100%',
	});
	//create app tabs
	var win1 = new Window(L('home')), win2 = new Window(L('settings'));

	var tab1 = Ti.UI.createTab({
		title : L('home'),
		icon : '/images/KS_nav_ui.png',
		window : win1
	});
	win1.containingTab = tab1;

	var tab2 = Ti.UI.createTab({
		title : L('settings'),
		icon : '/images/KS_nav_views.png',
		window : win2
	});
	win2.containingTab = tab2;

	self.addTab(tab1);
	self.addTab(tab2);

	self.addEventListener('open', function(e) {

		var playerWindow = Ti.UI.createWindow({
			width : '100%',
			height : 150,
			bottom : 0,
			backgroundColor : '#e5e5e5',
			visible : false,
			layout : 'vertical',
			zIndex : 100
		});
		playerWindow.open();
	});
	tab1.addEventListener('focus', function(e) {
		alert('1 Focus');
	});

	tab2.addEventListener('focus', function(e) {
		alert('2 Focus - this should fire, but it does not');
	});

	return self;
};

module.exports = ApplicationTabGroup;
