What just happened?
You added an event listener to the button so that when the button is clicked, an alert box is displayed. The Appcelerator documentation lists the events that are applicable for an object. You will use event listeners frequently in Titanium. They are explained in more detail in Chapter 4, Gluing Your App Together with Events, Variables, and Callbacks.
