ember.js - Ember currentViewBinding on ContainerView -

i have been trying learn ember , have spent lot of time referencing discourse code base on over github. anyway, wanted implement similar modal views method , don't understand why currentviewbinding isn't working.

the following combination of information referenced these links:

• ember.containerview documentation: binding view display
• discourse's modal_view.js file on github
• discourse's modal_controller.js file on github

app.headercontroller = ember.controller.extend   templatename: 'application/header'   needs: ['modal']    togglelogin: ->     console.log "headercontroller.togglelogin"     @get('controllers.modal').show(app.loginview.create())  app.modalcontroller = ember.controller.extend   show: (view) ->     @set('currentview', view)  app.modalview = ember.containerview   currentviewbinding: 'controller.currentview'    viewchanged: (->     console.log "modal view changed"   ).observes('controller.currentview')  app.loginview = ember.view.extend   templatename: 'modal/login' 

my views this:

<!-- application.hbs --> {{render header}} {{outlet}}  <!-- header.hbs --> <button {{action togglelogin}}>login</button> {{render modal}}  <!-- modal/login.hbs --> <h2>login form!!</h2> 

when app loads, 2 console logs "modal view changed", when click {{action togglelogin}} button in header template, nothing happens except console message "headercontroller.togglelogin".

what doing wrong or not how ember.containerview docs meant work?
