droppable options drop event issue

[ibrahimerbas]

when using droppable with options like following;
droppable:{data:DropTo,options:{drop:function(e,ui){//this is not firing;}}}

The problem is solved when I edit the source code as follows.

ko.bindingHandlers.droppable = {
init: function(element, valueAccessor, allBindingsAccessor, data, context) {
.......
var optionsDropEvent = droppableOptions.drop;
//set drop method
droppableOptions.drop = function(event, ui) {
var droppedItem = dataGet(ui.draggable[0], DRAGKEY) || dataGet(ui.draggable[0], ITEMKEY);
value(droppedItem);
if (optionsDropEvent )
optionsDropEvent(event, ui);
};
