I was using this at a hackathon and for some bizzar reason 2 out of 4 of our computer had no problem with observer for addition/changed/removed but 2 out of 4 of us could not get it to work even when we shared exact same code. (happening on both windows and mac). My computer used to work but then after trying it out at my work (same laptop) observer stopped working. I did subscribe and publish (and subscribe returns with right data), but for some reason observer does not work.

#20 Should fix the error when an observer registers a change

@bosung90 same thing happened to us 2 out of 4 of us too. It was because two of us were using version 0.1.1 and other two are using 0.1.2
