Template method in javascript

Question

Hi all,

I want, in javascript, to implement the template method pattern.

I have a PropertyDecorator with some subclasses: OpenButtonDecorator, SeeButtonDecorator and so on. I want to have in Property decorator the next function:

var build = function(){
   decorate(); //Abstract in PropertyDecorator, defined in subclasses
   return le.build();
}

How can I get this scenario working? Maybe I implemented wrong the inheritance :S (help with that too :) )

Thank you in advance.
