I followed the article on pre-populating data-grids from a data source. The grid renders correctly with initial values, but any edits made in the pre-populated rows (or entries in empty fields like Comments) are not saved when the form is submitted.
Example: If I fill Item Name, Amount, and Comments, then change Item Name or Amount, or add more Comments, the submission still contains the original pre-populated values instead of my edits.
How to fix this?
