Ember.run.bind is not working

I am trying to get ember.run.bind to work but it just doesn't seem to work, any idea? I have tried all combinations

_didInsertElement: Ember.on('didInsertElement', function () {
    Ember.run.bind(this, this.doSomething);
  })

or

_didInsertElement: Ember.on('didInsertElement', function () {
    Ember.run.bind(this, function() {
      this.doSomething();
    });
  })

or

_didInsertElement: Ember.on('didInsertElement', function () {
    var _this = this;
    Ember.run.bind(this, function() {
      _this.doSomething();
    });
  })
