Demo project

Just check the demo project,

We have abstract class ItemModel with property called Title, if there is ImplementItemMode class inherit from ItemModel and overwrite the Title property, the binding cannot work correctly in ListView RecycleElement CachingStrategy. At the first time, the ListView display correctly, but if you scroll the ListView, it cannot binding with the ImplementItemMode, it binding to ItemModel. 

It will work correctly in a Listview without RecycleElement.

That's happens on 3 platforms and 2.3.0
