Description

Steps to reproduce:
1. Set a breakpoint in the data setter of an ItemRenderer
2. Run your app
3. Scroll your list

Actual Results:
The data setter for all items, even items that are visible and not being recycled, is being set. This causes performance problems.

Expected Results:
Data setter should only be called when the item renderer is being created or recycled.

Workaround (if any):
