Sap.m.table sort / filter problem

I have to extend an existing application with custom sort and filter logic.

I applied that and it functions well.

The problem is when i try to remove the sorter / Filter.

The Filter / Sorter is removed but the table display is not refreshed.

The dislpay is not actualized and still shows the filtered / sorted data.

Is there a way to remove filtering / sorting which actualizes the table display / view?

Is it necessary to rerender the view?

If so can someone give me an hint how that has to be done?

Regards

Dirk
