Reload with scroll position

[ajayPris]

In our application, we have the ability to reload additional data while scrolling down the DataTable. Additionally, when we reload following a data retrieve, the reload() method resets the scroll position back to the top. At the moment, our content offset is set after the reload method, which makes it appear strange because the scroll position is set to the top and then after it will set our content offset.

Please add a toggle there so that we may choose not to reset the scroll or not
