        # affect!(integrator) = integrator.p.( somehow always reference model1 ).signal_value = 1.0

I’m not entirely sure what you’re trying to do, but did you try using an anonymous function affect! = (integrator) -> integrator.p.model[models].signal_value = 1.0? Defining dispatches of functions in a loop isn’t a great idea, while an anonymous function will act more naturally.
