Model doesn't halt if changes are made in child model code until you switch tabs

[arthurhjorth]

If you make a change to the child model code the model keeps going. But if you change tabs after, the parent model stops. Is it possible to make it happen as soon as we make a chance to the code? I'm assuming there's some sort of even listener sitting on that tab, but the callback function seems to be called in a different way than on the parent code tab.
