F7 v2 how to load url into popup view

Questions
1

This is the code I used to load a page into a new view on V1 but how can I do it in V2?

        var signup = myApp.popup(Template7.global.popTemplate);
	
	var view = myApp.addView($$(signup).find('.view'),{
	     dynamicNavbar:true,
	     domCache:true
	});

	view.router.load({url:'apps/users/register.html'});

var signup = app.popup.create({
  content: Template7.global.popTemplate,
  once: {
    opened: function (popup) {
      app.views.create(popup.$el.find('.view'), {
             url: '/some-route/',
	     iosDynamicNavbar:true,
	     stackPages: true,
      });
    },
  }
});

signup.open();

And you need to specify /some-route/ route in routes http://framework7.io/docs/routes.html like:

{
  path: '/some-route/',
  url: 'apps/users/register.html',
}

Thank you, however to get it to work I needed to change ‘once’ to ‘on’.
