Strange ListBox databinding

When databinding IList to  listbox, the setter won’t be triggered when calling IList.Add(). I had to use a local variable, then set it back to view property to trigger the setter.

The listbox won’t automaticlly refresh/update the changes in IList, the stupid way of working around is set datasource to null, then set it to new value.

Looks like using CuccencyManager looks more professional? Here is MS’s instruction for CurrencyManager.
