Bind events directly to the a, input, or button element. Use jQuery Mobile's virtual events, or bind standard JavaScript events, like change, focus, blur, etc.:
a
input
button
$( ".myButton" ).bind( "click", function(event, ui) { ... });
The form button plugin has the following custom events:
create
$('[type="submit"]').button({ create: function(event, ui) { ... } });
