javascript - Winjs List Dispose -


i trying optimise app windows 8. have winjs.binding.list , page display filtered projection of list. every time access page filter different want dispose of list when leave page.

here filter:

            filteredlistviewitems = data.items.createfiltered(function (item) {                 if (item.project === certainproject) {                         return item;                 };             });

when leave page call:

           filteredlistviewitems.dispose();

however if put breakpoint inside function still runs every time add item.

how can remove altogether?
