reset wizard when page reload

[enneffesviluppo]

on v5 when i reload the page the wizard start from last visited step, and not from first step.
I tried add this code
$(window).on('beforeunload', function() {
// Reset Smart Wizard state
$wizard.smartWizard('reset');
$wizard.smartWizard("goToStep", 0);
return 'Are you sure you want to leave?';
});

but doesn't work
any idea?
