[SOLVED] Active state : click two times!

Hi,

On a click event for input or button,

$$('.convert-form-to-data').on('click', function(ev){
 });

the callback is called two times, one of the events targets the button with the class .active-state, and the secondth targets the button without the class .active-state.

 <button type="submit" class="button convert-form-to-data">Découvrir les résultats</button>

Have i misconfigured F7 or it is the expected behaviour?

Thanks,

solved with this option :

touch: {
  fastClicksExclude:'.fc_excluded'
}
