Set arbitrary properties of the checkbox control.
Behavior is the same as when setting the respective property in the configurator editor.
Some properties are not allowed to be set here because they have a dedicated method which should be used instead.
E.g. setting visible is not allowed because CheckboxV1.setVisible should be used instead.
See CustomControl.onRendered for detailed information on what you can do with this listener and what it is not meant for.
Also see OnRenderedCallback for important information regarding the
elementwhich is passed to the callback.
