Object constructors inside object constructors

Let's say I have the following script:

var A = function() {
  this.b = "asdf";
  this.c = function() {
    this.source = "asd";
    this.data = function() {
      var response;
      $.getJSON(this.source, function(data) {
        response = data;
      });
      return response;
    };
  };
};

The reason I made those closures is that I have other objects and variables inside A, making an object-oriented app. I have some doubts regarding that script:

Note: the purpose is to, on new A(), generate an object like this:

{
  b: "asdf",
  c: {
    source: "qwerty",
    data: {
      jsondata1: "jsonvalue1",
      jsondata2: 3,
      // ...
    }
  }
}

but I know instance.c will still be a constructor function, and I have no clue how to make it an object inside another.

This should work

var A = function() {
    var me = this; //<-- to let you refer to b inside the c function
    me.b = "asdf";
    me.c = new function() { // <-- added new here
        this.source = me.b + 'abc';
        this.data = function() {
            var response;
            $.getJSON(this.source, function(data) {
                response = data;
            });
            return response;
        };
    };
};

a = new A();

a.b returns "asdf" and a.c.source returns "asdfabc". a.c.data would still be the function though.
