Describe the bug

Using RadListView with ObservableArray when I change the array, the index won't follow the changes. Everything else works as expected.

To Reproduce

The bug is 100% reproducible using this sample:
https://play.nativescript.org/?template=play-ng&id=sbm9Rh&v=3

1. Tap on the items, the appearing text should match.
2. Delete: Item 3 by clicking X
3. Tap on Item 4 or Item 5, the appearing text won't match.

Expected behavior

When the ObservableArray changes, the index should represent the belonging item.
