Disable CheckBoxGroup listener when custom renderer is used

I need to add help about items in the CheckBoxGroup. I have a custom wrapper which adds a button to the right of the wrapped component, which when clicked opens help dialogue. I use custom renderer in CheckBoxGroup to add the helper wrapper to items, so that user can get help. However it doesn’t work, since events do not propagate to rendered helper button. How to disable that default CheckBoxGroup item listener on a custom component and leave only on the checkbox square itself? (or any other solution)

Please share your code so that we’re able to help you.
