Kevin, I am using the same technique and it works just fine.
The featureAdded callback gets called during
DrawFeature.drawFeature(). This function does not appear to be in
your stack trace (nor is toggle()) so that isn't your problem at this
point.
It looks like you have some other code hanging around that is causing
you problems - something that is handling the dblclick it looks like.
Cheers
Paul
