Hi, There are a couple of problems there, not least that I don't see anywhere that a's `to_execute` property is set, so as far as I can see b would get an undefined value. Did you mean `do_something`?
But I suspect that's a copy-and-paste error. The basic problem is that you're passing a function without any context. Functions are just functions, the `this` value does not follow them around as it (seems to) in some other languages. In JavaScript, `this` is set purely by how you *call* a function. There are several ways to deal with that, including Prototype's Function#bind[1]. I wrote up a full description of this issue[2] in my blog a while back.
