Hello! I’m trying to hide the page toolbar in the pageinit section when I load the page. Does not work. If I make a button on a page or I link to an event of any element - it works. How to be?

pageInit: function () {
     app.toolbar.hide('.toolbar');   // not work

     $$('#some_element').on('click', function() {
        app.toolbar.hide('.toolbar');   // work
     });
}

Page content is tabs, toolbar:

  <div class="toolbar tabbar">
    <div class="toolbar-inner">
      <a href="#tab-1" class="tab-link tab-link-active">tab_name1</a>
      <a href="#tab-2" class="tab-link">tab_name2</a>
      <a href="#tab-3" class="tab-link">tab_name3</a>
    </div>
  </div>

{
  path: '/path/',
  url: 'url',
  on:{
    pageInit:function(e,page){
      setTimeout(function(){
        app.toolbar.hide('.toolbar');
      },0);
    }
  }
}

or

{
  path: '/path/',
  url: 'url',
  on:{
    pageAfterIn:function(e,page){
      app.toolbar.hide('.toolbar');
    }
  }
}
