They work well, but sometimes come at the problem from a direction other than what one might first expect. Or might want for their specific case. I have never used AjaxSortableList, but I suspect this is what you are seeing. From looking at the code, AjaxSortableList re-orders a list. It does not tell your code what elements to move or what was moved, it just moves them. Then it calls the method bound to action. You could bind action, and in this method iterate over the list and manually set the new index to reflect it's place in the list. Or you could do that in the method on your page that sets the list when AjaxSortableList changes it.
