jQuery document.ready callback

To fix the hint error you need to append Ember. to the second jQuery call.

App = Ember.Application.extend({
  modulePrefix: config.modulePrefix,
  podModulePrefix: config.podModulePrefix,
  Resolver,
  ready: function() {
    Ember.$(".bookashko-logo4-bklens1").click( function() {
        Ember.$(this).toggleClass("bookashko-logo4-bklens2");
    });
  }
});

Is this .bookashko-logo4-bkklens1 available in the DOM at the time this runs? Eg: Is it within the index.html file?
