method inside method

[johns221b]

function A(){
this.B=_B;
}

function _B(){
this.C=_C;
}
function _C(){
alert("IN");
}

var a=new A();
a.B().C();

variable 'a' is an instance of class A().
Trying to call method _C() as below
a.B().C();

which is throwing error.
requirment is to call something like
Menu.Options(0).Hide();

function A(){
this.B=_B;
}

function _B(){
this.C=_C;
return this;
}
function _C(){
alert("IN");
}

var a=new A();
a.B().C();

B() just calls the function, it doesn't create a new object. The return this does a similar thing to

new A()
