Data Grid 2 - Text Filter is not working

We have a Data Grid 2 Table placed on a Page. For the First Column we have as Attribute a Calculated Attribute – a String, so Should be fine. The Cell content is Custom because we need some styled presentation The Text Search Widget added to this column has no impact, no matter what we type choose or change. No Errors, NO Hints in the documents for such use cases as exceptions.   Any Ideas?

I believe you need to be on 9.4 or higher to use the widget.
