Settings the context of 'this' in IIFE

I want to bind the 'this' context of the following code to the Collection prototype object, but right now it refers to the window object instead.

So far I have tried to wrap the function definition as a IIFE, but this doesn't change the context.

My code

Mongo.Collection.prototype.bulk = (function(){
  var context = this; <------- should refer to the prototype's context and not the object 'bulk'

  return {
    insert: function(documents, options) {

    },
    update: function() {

    },
    upsert: function() {

    }
  };
})();

How can this be accomplished?

RGraham's comment is the correct answer. There's no need for the IIFE. You can just do a plain prototype.fn = function() { var context = this; }

But if (for whatever reason) you can't do that... then you can pass whatever you want to use as the context as a parameter to the IIFE:

Mongo.Collection.prototype.bulk = (function(context){
  return {
    insert: function(documents, options) {

    },
    update: function() {

    },
    upsert: function() {

    }
  };
})(Mongo.Collection.prototype);
