Can't seem to get expire to work...

[raptor235]

I'm attaching the livequery in the following manner

$('body').livequery( '.clasname', function(){
console.info('Created in DOM');
console.log(arguments);
Sidekick.Events.trigger('expireWaitFor');
},function(){
console.info('Removed from DOM');
console.log(arguments);
});

then when an element is found I trigger the expire event as

$('body').expire( '.clasname' );

I run a test after wards and I continue to get logs firing whenever I add the class classname to anything within the body or take them out... so it seems that I'm not using the expire function properly...
