How to reload current route in Ember.js?

It seems the solution in the answer won’t work for current route.
I had a same issue and tried the solution here and it worked.

In your route.

actions: {
  sessionChanged: function() {
    this.refresh();
  }
}

and in your controller.

observeSession: function() {
  this.send("sessionChanged");
}.observes("session.isAuthenticated"),
