Subscriptions are now workinggit add public/javascripts/subscription.js! If you watch the database (dev) you should see the subscription be added and unadded. Please for testing purposes always leave the status unsubscribed when you are done testing as the setting of the state of the button initially is not in place as of yet. If you have problems with the button itself you may not have your application.conf file anymore. Readd this with your database pointing at dev and the problem should be solved.
