How to get the name of a dynamically created button using and OnClick event in Delphi?

I need assistance for trying to get the name of a dynamically created button using and OnClick event in Delphi.

I am then want to use the name of that button and store it in a global variable.

This is where I am currently:

procedure TMap.FormShow(Sender: TObject);
var
btnCache : TButton;
begin
 btnCache := TButton.Create(imgAerial);
 with btnCache do
 begin
  onclick := ClickButton;
 end;

procedure TMap.ClickButton(Sender: TObject);
begin
//Code for getting the name of the button
end;

The button's name can be retrieved by casting Sender to the type that introduces Name. That is TComponent. 

(Sender as TComponent).Name

Don't expect this name to be very informative since your code does not assign a name to the button. As the code is written in the question, the dynamically created button has no name.
