Beta 3.0.0.0 What needs to be set to enable WebDBDataGrid editing and programmed filtering?

The attached demo project is a modification of my previous one, but using a TWebDBDataGrid and a TWebClientDataSet instead of TWebDataGrid. Sorting and filtering from the UI both work as expected, but editing and programmed filtering both do not work at all. What am I missing this time?
