SelectRenderer options list different between rows of same column

Hello

Im having trouble refreshing the option list in a grid column SelectRenderer addon.
SelectRenderer is set on a Grid column, and I attempt to update it everytime the options list is changed. It could be expanded, or it could become shorter.

Steps:
1. A column is programmatically added to Grid, the SelectRenderer is added to this column with an empty set of options.
2. A row is added to Grid, then the SelectRenderer is re-added to Grid column with an expanded set of options. This works, the SelectRenderer option list now has one item.
3. A secod row is added, and SelectRenderer is re-added to Grid column with expanded set of options. This does not work:
Result:
Row 1 in Column 1 has one option in SelectRenderer
Row 2 in Column 1 SelectRenderer has two options

How do I "refresh" the SelectRenderer list of options across entire Grid column?

Thanks!
