Call Mixin method when overriding

ember.js

Solution

In order to call `this._super` from `Ember.run.next` try the following,

http://emberjs.jsbin.com/docig/3/edit

App.MyCustomMixin = Ember.Mixin.create({
  testFunc:function(){
    alert('original mixin testFunc');
  },
  actions:{
    testAction:function(){
      alert('original mixin testAction');
    }
  }
});

App.IndexController = Ember.Controller.extend(App.MyCustomMixin,{
  testFunc:function(){
    alert('overriden mixin testFunc');

    var orig_func = this._super;
    Ember.run.next(function(){
      orig_func();
    });
  },
  actions:{
    test:function(){
      this.testFunc();
    },
    testAction:function(){
      alert('overriden mixin testAction');
      var orig_func = this._super;
      Ember.run.next(function(){
        orig_func();
      });
    }
  }
});

Problem

I've got a Mixin in my controller that has a particular action. I need to override this action, do some stuff, and then call the original action provided by the Mixin. How can I do this? `this._super()` doesn't seem to work in this case (which does make sense, as it's meant to call the superclass' implementation, not a Mixin's).
