Change detection in js files not working in ubuntu 15.10

Error fixed, after update i had an issue with the amount of watches in my OS, the solution:
1. First try npm dedupe to release some watches that could be left as garbage.
2. If the first doesn't work try this to increase your OS limit on watches: echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
