Field Table values dosen't refreshes for particular stock item

Hello Experts.
I have created this collection under stock item with remarks as values. I want to select one of the remarks (for corresponding item name) from table in a new column for each inventory entry at the time of voucher creation.

It works fine for 1st stock item, But popup table gets the list of remarks for the first stock item every time. Where am I going wrong? Just give some clue.. I will figure it out.
To me it seems the collection gets build in start with remarks from 1st stock item. But then it never refreshes for next Inventory Items. What to do Sir?

ThankYou Experts
