WebIDE - Plugin development

HI,

Im developing webIDE plugin with UI, in the service I initiate the view .

In the UI I've button with press event which invoke my controller.(this is working)

My question is how should I call from the controller to the service.

I need to invoke some method inside the service from the controller

I didnt find any docs about it, any reference/example which  show how can I call from

the controller to WebIDE service will be very helpful

Thanks,

Joerg
