Thanks Bryan - reproducer attached.
The DataTable is not in a tab.
To be more explicit, I believe I am observing that:
• A JS Callback is capable of updating the datasource behind a widget but not the rendering of that widget. (I think I observed something similar with a multiselect widget as well but this reproducer is just for the datatable.)
• A python callback is capable of updating both the datasource and the rendering of the widget.
See code/comments for full detail.

Unless your DataTable is in a Tab, then I don't think the linked issue could be related. That is a very narrow and specific issue, which is why it has not been prioritized. I've checked out various DataTable examples with 0.12.16dev3 and they are all working and updating as expected, so a complete reproducer will definitely be needed to investigate.
