I want to make a WinJS.UI.ListView paging, paging is working at the time I reached the last scroll index. when the index reached last, I am requesting more data to the server with the API. is this possible?
You'll want to look at creating your own custom data source to handle this. See the MSDN article How to create a custom data source:

and the accompanying sample code:
http://code.msdn.microsoft.com/windowsapps/ListView-custom-data-4dcfb128
In short, you'll be creating a class that implements the IListDataAdapter interface and using it with your own derivation of the VirtualizedDataSource class. The ListView will take care of the visual display and will call your code when it needs more data.
