TIWGrid + TIWBSButton

[Rassamaha78]

Hello. I am rewriting my project from regular IW to IWBootstrap (3).
I have a table (TIWGRid) in which several dynamic buttons are created, the code was like this:

Code:

  with grdGetNumber.Cell[ i, 4 ] do
    begin
     Control := TIWButton.Create( Self );

     with TIWButton( Control ) do
      begin
       Caption := 'Buy';
       Width  := 60;
       Height := 24;
       Name   := 'BTNGETNUMBER' + IntToStr( i );
       OnAsyncClick := OnBuyKeyAsyncClick;
       Tag    := i;
      end;

    end;

Now I want to use TIWBSButton, I added Parent to the code:

Code:

     with TIWBSButton( Control ) do
      begin
       Parent  := TWinControl( grdGetNumber );
       BSButtonStyle := bsbsPrimary;
       ...
      end;

The buttons on the page are displayed, but the page does not load to the end, the loading animation icon is constantly visible. How to add TIWBSButton to TIWGrid ?
