Receive Notification after Binding Configuration was Saved

I’m currently implementing a binding that requires the IP address of a webserver for auto discovery. Therefore I have added a parameter to the binding.xml file which I can set from the admin UI (Configuration -> Bindings -> Configure). My problem is that I didn’t find any way on how to receive the information that the configuration was saved/updated.

I have tried a few things as implementing org.eclipse.smarthome.config.core.status.ConfigStatusCallback or org.eclipse.smarthome.core.events.EventSubscriber but without any luck so far.

I guess with openhab1 this could have been achieved by implementing the “modified” method as described in the section > Global Binding Configuration in https://github.com/openhab/openhab/wiki/How-To-Implement-A-Binding

Hope you can help me with this…
