Add events for click on step label

[niutech]

When using an editable stepper, I want to invoke form fields validation on leaving the current step. For now, I can handle it using events: onstepnext and onstepback. Please add a similar event on clicking the step label at the top, where I would be able to cancel moving to another step depending on my condition.

Agreed, another event, more generic like "onStepperChange", which could be triggered either when clicking the step label or the prev/next would be a nice addition to the existing events: https://ahlechandre.github.io/mdl-stepper/component/

So far, you have to add several handler, including "onclick" events on labels to achieve that

Thanks,
