sortable remove

sortable remove


I've got to be missing something obvious here, but I can't see it. How
do I get 'remove' to fire on a sortable?
I've got a sortable setup with the following code:
$('#sorted-images').sortable({
    cursor: 'move',
    items: 'div.scraped-image',
    opacity: 0.8,
    placeholder: 'image-outline',
    revert: false,
    remove: function(e, ui) {
        console.info( 'REMOVE: '+ e );
    },
    stop: function(e, ui) {
        save('#sorted-images');
    }
});
As you can see, I'm using Firebug to see if 'remove' is getting
called, and it never is. Any help would be appreciated. It's not
listed in the UI docs, so I'm not sure if I'm even using it correctly.
