How to access class variables from inner prototype - javascript

I might not be clear with my title of the question. Sorry for that.

Here is what I wanted to do.

I'm trying to use prototyping pattern in javascript. I created a class as following.

var MyClass = null;
(function() {
    MyClass = function() {
        this.clsVar = "I'm inside constructor";
    };

    MyClass.prototype = {
        constructor: MyClass,
        myFunc1: function() {

            console.log("I'm func1 accessing constructor variable : " + this.clsVar);
        },
        nested: {
            myFunc2: function() {
                console.log("I'm func2 accessing constructor variable : " + this.clsVar); // I know, this will never point to the class scope
            }
        }
    }
}())

I'm creating an object.

var my = new MyClass();

my.myFunc1(); // which prints "I'm func1 accessing constructor variable : I'm inside constructor" 

my.nested.myFunc1(); // as expected, it prints "I'm func2 accessing constructor variable : undefined

All I am trying to do is, I should be able to access clsVar from nested.myFunc2

is that possible.? Any help is greatly appreciated and needed.
Thanks.
