Uninstall plugin component with main application

I have WIX installer for my main application with custom bootstrapper. I have written plugin component (dll) which has separate installer. Plugin dll is deployed thought its own installer at same location as main application deployment. It also marks entry in control panel and in registry.

I want to inform user during uninstall of main application if he wishes to uninstall plugin as well (if exist), if yes- it should uninstall both main and plugin, otherwise only main application.

My question is how do I chain uninstall of Plugin component along with main application?
