[TIMOB-24531] Android: onBackPressed behaviour does not work correctly

var win = Ti.UI.createWindow({
    backgroundColor: '#fff'
});

var lbl = Ti.UI.createLabel({
	text:"window 1"
})

var btn = Ti.UI.createButton({
	title:"create",
	bottom:10
});

btn.addEventListener("click",function(){
	var win2 = Ti.UI.createWindow({
	    backgroundColor: '#fff'
	});
	var lbl2 = Ti.UI.createLabel({
		text:"Close to go to window 1", color:"#000"
	});
	win2.add(lbl2);
	win2.open();
})

win.add(btn);
win.add(lbl);
win.open();
