Iscroll - Jquery - Get position on a list item

Question

The error I'm having is the following:

To the right of my page, I have a list of interesting points (displayed on a map to the left of the page). Because the list is so long, I am using iScroll 4 (great plugin).

However, what I would like to do is fire an event when the user has scrolled the list, so I can check which items are currently visible to the user. iScroll already has an event set up for that, so I have a function that fires when needed. However, I cannot seem to get the proper coordinates of my list items.

What happens is the following:

1. When the list loads, I get an .offset() value for the first element. offset.top = 35, because my list starts 35px lower than the top edge of the page. This is good.
2. When I scroll the list; say I pull it down for 500px; I would expect the new location to be 35px - 500px = -465px. However, it sill says 35. Scrolling though the list does not affect the elemen'ts coordinates even though it has moved.

How can I get the actual coordinates?
