Scrolling while dragging an event from top to bottom

I used the Fullcalendar-2.0.0 plugin to create a page that shows calendar events. Everything works fine. But just wanted to know if there is a way to scroll the calendar when dragging certain events? It works when we drag the event in the browser, but I want to do the same for mobile, but I can't get it to work.

Any help would be greatly appreciated. Thank.
