Edit History

I noticed that there isn't a way to delate or reset the field of product-customization.tpl 

I thought to add something like this in the product-customization.tpl, but it doesn't work. Any suggestions? 
 

 <div class="clearfix">
            <button class="btn btn-primary float-xs-right" type="submit" name="submitCustomizedData">{l s='Save Customization' d='Shop.Theme.Actions'}</button>
<button class="button btn btn-default button button-small" name="resetCustomization" value="1">
    <span>{l s='Reset customization'}</span>
</button>
          </div>

When I click it, it goes in the cart page!
