I am working on a POC and do not want to write any specific transaction processing functions. Created assets, participants etc. and all, so the model is ready. Generated rest api using hyperledger composer-rest-server. The frontend is developed in simple html/javascript. the problem is that i need events also available whenver i CRUD using composer generated APIs, but not able to figure out how. IS it that to capture events, we need to create assets using transaction processing functions only and not via composer rest server apis - a little novice kinda question but i am stuck in this thought.
