When Ext. vertical scrolling is stuck, how can I force to fetch more data via workflow aciton?

I have my repeating group set within a fixed size of group. Layout style of Ext. vertical scrolling is supposed to fetch more data when it scrolled down. But the issue is that it doesn’t respond to the scrolling action on mobile browser as you can see it here.

I guess it caused by the repeating group is placed within a fixed size of a container(group) so that bubble(or browser) assume it is an end of the data.

I am now wondering if I can find a way to fetch more data with some kind trick on workflow.
Did someone encounter similar situation?

Thanks in advance.

A refresh button that does display data in a repeating group would work

Thanks for the advise, Chris.
Did you mean one of those?

I’m afraid it is not applicable to my situation.
If I don’t seem to be getting the point across, could you add some details?
Thank you.
