I have a WinJS.Binding.List
I populate the list with data from an Array.
When I want to edit the item I use: list.getItem()
I then edit the data of the item: item.title = "New Title"
I then cant see this change on the tile until I refresh the page.
I am currently using list.setAs() to update the item which is working fine apart from the small issue that you dont get an item update animation.
