Here's your problem.  You didn't give it the right prototype.

Things used to default to "if you pass no prototype and just the class 
we'll do some fragile lookup to try to figure out the right prototype", 
but that went away in https://bugzilla.mozilla.org/show_bug.cgi?id=1125567

So you need to pass in the right prototype object here.
