Hi, I'm having hard time trying to make data-validator to work. I've tried using it in the "Continue" button with a dummy false-returning function but it continues to the next step. In documentation it's not used at all so...is data-validator it working at all? According to other posts, seems it hasn't been working since some versions back.

function someFunction() {
     return false; //this should prevent to continue, but does nothing.
}

<div class="step-actions">
            <button class="waves-effect waves-dark btn btn-sm btn-primary next-step" data-validator="someFunction">CONTINUE</button>
          </div>

I tried to use data-feedback as a workaround but whenever my customized validation function returns false (therefore i don't call .nextStep()) the loading screen stays forever; I had to call .destroyFeedback() to overcome this stituation; but I wanna know if there's a better way to handle when data-feedback validations fail, or how to correctly use data-validator?

function someFunction() {
    if(validationFunction()){
         $('#my-stepper').nextStep();
     }
     else{
         $('#my-stepper').destroyFeedback();
     }
}
<div class="step-actions">
        <button class="waves-effect waves-dark btn btn-sm btn-primary next-step" data-feedback="someFunction">CONTINUE</button>
      </div>

Thanks
