Firemonkey Livebindings StringGrid (Grid) insert components into cells

For the convenience of the user, I'm trying to insert into the Grid CalendarEdit .
While thinking about 2 options:

1. Make it so that all lines would have CalendarEdit .
   Problem : I create a column of the required format :

    TDateColumn = class(TColumn) protected function CreateCellControl: TStyledControl; override; end; function TDateColumn.CreateCellControl: TStyledControl; begin Result := TDateCell.Create(grid); Result.Parent := grid; end; 

   I add it to the Grid :

    procedure TForm1.FormCreate(Sender: TObject); var cec: TDateColumn; begin cec:=TDateColumn.Create(grid1); grid1.AddObject(cec); end; 

   everything shows ok. But when linked with liveBindings :

    LinkGridToDataSource1.Columns.Items[LinkGridToDataSource1.Columns.Count-1].MemberName:='date';` 

   the component disappears, and a plain text string appears. I found out that during liveBindings in TLinkGridToDataSourceColumns the type of the column is once again indicated and there it stands as Default, I don’t understand how to add / create the type of column I need.

2. To do so, when clicking on a cell on top of it, the control was drawn, and when clicked, it would disappear to another location and the value would fall into the Grid .
   Problem : I did not find how to determine the coordinates and dimensions of a specific cell to draw on top of it.
