First, you need to add to Form.Element.Methods (this will affect
"input", "select" and "textarea" elements). Then, you just need to
call Element.addMethods() (this will actually extend elements):
Object.extend(Form.Element.Methods, {
...
});
Element.addMethods();
Best,

Then, you just call Element.addMethods();
