The only way that I've been able to get the IDs is like so:
onChange: function(){
var text = Sortable.serialize("list");
var first_id = (text.substr(8,4));
var second_id = (text.substr(21,4));
}
In this case the lengths of the IDs is 4 digits. The problem with the
above is that you can't get the ID of the item that was added to the
list the most recently. I'm sure there's a better way...
