I am launching my app from my service app, so to detect that new launch request, i need to implement – AppControlSignal()

So I am writing this piece of code – 

But this is giving compilation error –

D:/Tizen/tools/smart-build-interface/../../platforms/tizen-4.0/mobile/rootstraps/mobile-4.0-emulator.core/usr/include\dali/public-api/signals/callback.h:698:5: error: called object type ‘Dali::Signal<void (Dali::Application &, void *)> (ClientController::*)(Dali::Application &)’ is not a function or function pointer

    (*object)( param1, param2 );
