bind function not working on a sortable

bind function not working on a sortable

I'm trying to handle the sort-stop event.  I am able to specify the event handler on initialization of the sortable.

        // This works
        $("#sortable").sortable({stop: function(e,ui){alert("sort stopped");}});

but I am unable to use the find function to accomplish the same.

        // This has no affect  
        $('#sortable').bind('sortstop',function(e,u){alert('sortstopped);});

Advice is appreciated.
