How to disable a link button in jQuery Mobile?

I have a jQuery Mobile Beta 1 website with jQuery 1.6.1 link button like this:

<a id="subselection" href="#" data-role="button" data-theme="b">TEST</a>

And in document.ready i set the click event:

$('#subselection').livequery("click", function(){
  alert('test');
});

I whant to disable this "link button" and i tried

$('#subselection').button('disable')

And that command set the button style like it is disabled but the click event works.

I have also tried

$('#subselection').prop('disabled', true);

and $('#subselection').prop('disabled'); gives true but its not disabled.

Someone has a good idea.
