[jQuery] Learning about functions and methods (I am confused)


Hy
(function($){
    $.myPlugin = function(){
     holla: function(){
         alert('holla');
     }
    }
    $.myPlugin.hello = function(){
     alert('hello von Plugin');
    }
})(jQuery);
// Works finde:
$.myPlugin.hello();
// It does not work. Why?
$.myPlugin.holla();
Is there a posibility to write a method in:
... snip
$.myPlugin = function(){
     // Write methode here
     }
    }
...snip
So that
$.myPlugin.holla();
will work?
Thanks!
