[jQuery] subclass

[Anjanesh]

How do I create a subclass ?

(function($) {
    $.fn.myname = function(){
        return this.each(function(){
            });
        }
    })(jQuery);


(function($) {
    $.fn.myname.subname = function(){
        return this.each(function(){
            });
        }
    })(jQuery);

$("#id1").myname.subname();

I get

this.each is not a function
