RobotStudio event

SmartComponent does not receive simulation ticks

Hi,
i have created a SmartComponent with CodeBehind, and i want to do something on every simulation tick. So i set "CanBeSimulated" in the xml file to true, and wrote my code into the method OnSimulationStep, but the method is never called during a simulation run. So where is the problem, did i miss something?
I am using RS 5.15 if this helps.

Regards,
Matthias
