Dynamic Update doesn't work on multiple pages

[megasoft78]

Hi,
I'm trying to make the control update during the scroll but it's not working.
It seems to duplicate the items even if the data provided is correct.

I attached a modified version of dynamic-load.tsx and a video.

Could you please help me?

I was able to fix this by replacing the updateItems function:
