I'm not clear on what the problem is here. Will you please provide me a
sample app of this?

If you want a refresh you call the refresh method.

I suspect you mean something else? More details please.

I have no idea what is going on here. It sounds like the app is doing some
pretty special stuff. I'd like to see a sampling of this as well and then I
may be able to address the performance of it. I certainly am not going to be
able to help you here based on this little information.
