ZURB Joyride - reset 'count' when tour is finished

gistfile1.js

/* problem: when ZURB's Joyride tour ends, if the user causes it to run again, the 
  'count' seems to be messed up

   solution: the plugin creates divs with ids in the pattern: 'joyRidePopup' + index
   and then iterates through them - running the iteration again recreates the divs &
   re-runs and gets confused.  So you use postRideCallback (one of the options, see
   http://www.zurb.com/playground/jquery-joyride-feature-tour-plugin - step 5 for more info)
   to remove those divs when the ride ends

   this GIST shows how to bind joyride to a 'HELP' button that will trigger the tour when clicked.

var helpMe  =  function helpInstance(){
        $('div[id^="joyRidePopup"]').remove(); /* in case button is clicked
                                                  while tour is running  */
        $(document).joyride(
            {
               // add any other option listed at the playground
               // http://www.zurb.com/playground/jquery-joyride-feature-tour-plugin          
                'postRideCallback': function(){
                    $('div[id^="joyRidePopup"]').remove();
                 }       // a method to call once the tour closes
            });
    };  //end helpInstance()

$("#help").on('click', helpMe);

Help,

When you enter the website, the tour is successful, but when I run it with the button does not work.

What am I doing wrong?

$(window).load(function() {

$('#GuiaUsuariJoyride').joyride({
    tipAnimation: "fade",
    tipAnimationFadeSpeed: 300,
    cookieName: 'myname',
    cookieDomain: 'mydomain.com'
});

});

$(document).ready(function() {

    $('#icona_ajuda').click(function(){

    $('div[id^="joyRidePopup"]').remove(); /* in case button is clicked
                                              while tour is running  */
    $('#GuiaUsuariJoyride').joyride({
           // add any other option listed at the playground
    'tipAnimation': "fade",
    'tipAnimationFadeSpeed': 300,
    'cookieName': 'myname',
    'cookieDomain': 'mydomain.com',
            'postRideCallback': function(){
                $('div[id^="joyRidePopup"]').remove();
             }       // a method to call once the tour closes
    });
});

}
