Bind events directly to the set container, typically a div
element. Use jQuery Mobile's virtual events, or bind standard JavaScript events, like change, focus, blur, etc.:
$( ".selector" ).on( "create", function(event, ui) {
...
});
The collapsible set plugin has the following custom event:
create
triggered when a collapsible set is created
$( ".selector" ).collapsibleset({
create: function(event, ui) { ... }
});
