var win1 = Ti.UI.createWindow({
	backgroundColor : "white",
});

var w = Ti.UI.createWindow({
	backgroundColor : 'purple'
});
var b = Ti.UI.createButton({
	title : 'Close',
	width : 100,
	height : 30
});
b.addEventListener('click', function() {
	w.close();
});
w.add(b);

w.addEventListener("close", function() {
	alert("hello");
});

var b1 = Ti.UI.createButton({
