The click handler of the toolbar command. Used for custom toolbar commands.

The name of the toolbar command. Can be either a built-in ("create", "excel", or "pdf") or a custom string. The name is output in the HTML as a value of the data-command attribute of the button.
The text that is displayed by the command button. If not set, the TreeList will use the name` option as the button text instead.
