How can I intercept correctly the next event on each step?

Hi there, how can I intercept correctly the next event on each step? I see there's onStepChange() callback but I can't get how it works. Should I provide an onStepChange function in-scope for each controller involved in the multistep form?

onStepChange is on the directive itself, it is an external function you can pass to the directive so it gets called back on each step change. It is not on the scope of the directive or its steps.

All right ok. Can you give me a smart way to intercept programmatically "next" and "previous" event on each step?

You can try to decorate the nextStep and prevStep methods of multiStepFormInstance.

Would you point me to the right direction to do that? Or make me an example...thanks.
