I am having a really hard time trying to get any of the modal windows to work in my app. I have copied the code exactly from Kitchen Sink, and it still does not work.

Here is the code I'm trying to use:

var adView = Ti.UI.createButton({
    title:'Button',
    width:320,
    height:60,
    opacity:1.0,
    left:0,
    top:400
});

adView.addEventListener('click', function()
{

    var w = Titanium.UI.createWindow({
        backgroundColor:'#336699'
    });

    // create a button to close window
    var b = Titanium.UI.createButton({
        title:'Close',
        height:30,
        width:150
    });
    w.add(b);
    b.addEventListener('click', function()
    {
        w.close();
    });

    w.open();
});

win1.add(adView);

When I click on the button, it does nothing. What am I doing wrong?
