It seems to me that it's a matter of which element 'this' refers to.
In this case, when the 'keyup' fires, 'this' will refer to $
('some_element'), not to the element you probably expected.
Take a look at http://www.prototypejs.org/api/function
and try this:
$('some_element').observe('keyup', this.handler.bind(this));
If anyone has a more elegant way to solve this, please let me know.
