That is default WhenAction.

WhenAction, the basic Callback defined in Ctrl, is called by most (not all) widgets each time when user (!) changes the status of widget. Usually, with the exception of Button, "changes the status of widget" means that the Value of widget has changed.

Just use <<= to assign the callback.
