Ember observer not working when observes property of other controller

I want to access the IsOpen property that is set in my ApplicationController in my EventsController , but more than that , I want to listen for changes in it , so I'm using the following code :

isOpen: Ember.observer('application.isOpen', function () {
  console.log('test');
}),

But is not firing at all.

In my ApplicationController i have the following:

export default Ember.Controller.extend({
  isOpen: true,

  actions: {
      toggleSidebar () {
       this.toggleProperty('isOpen');
      }
   }
});

Am i missing some configuration?

UPDATE:

What i'm trying to do:

In my application template, i'm calling two components, the sidebar and the navbar component. In the navbar component, i have a button, each will send a action to ApplicationController, in order to make the sidebar toggle.

Like this:

ApplicationTemplate:

{{#if session.isAuthenticated}}
	{{pc-sidebar
		isVisible=showWrappers
		isOpen=isOpen
	}}
	{{pc-navbar
		isVisible=showWrappers
		isOpen=isOpen
		action='toggleSidebar'
	}}
{{/if}}
{{outlet}}

So, when i click in the button in my navbav, i send a action to ApplicationController:

actions: {
  toggleSidebar () {
     this.sendAction('action');
  }
}

And in my application controller, i just update the isOpen property:

  isOpen: true,
  actions: {
     toggleSidebar () {
       this.toggleProperty('isOpen');
     }
  }

Now the problem:

I need toggle the main too, each is wrapping all the content, BUT.... the MAIN is not in the application template, because only a few templates need it , that would be the case of EventTemplate:

<main class="main">
  <!-- content of event template here -->
</main>

So.. my solution was make the main a component, and call like this:

{{#main-main isOpen=isOpen}}
  <!-- content of event template here -->
{{/main-main}}

Now.. i need listen to isOpen that was define in ApplicationController, and i'm struggling with this..

Thanks.
