Dynamic create TUniRadioGroup.

following code,  the columns doesn't divide to 6. 

what's wrong?

 

  RemoveControl(rgEmp2);  

  rgEmp2 := TUniRadioGroup(InsertControl(TUniRadioGroup.Create(Self)));

  rgEmp2.ClientEvents.ExtEvents.Add(

    'radioGroup.beforerender=function radioGroup.beforerender(sender, eOpts)'

    + #13#10

    + '{'

    + #13#10

    + 'sender.columns = 6'

    + #13#10

    + '}'

  ); 

 

 

  if not cdsDepMan.IsEmpty then

  begin

    cdsDepMan.First;

    while not cdsDepMan.Eof do

    begin

      rgEmp2.Items.Add(cdsDepManempname.AsString);

      cdsDepMan.Next;

    end;

  end;
