How to sync Embersj in docker container for development

I am trying to run emberjs in a docker container. I am using the docker-compose.yml I defined Volume as a path on host machine So after doing docker-compose up, ember starts and work. then I do some small code change, for example change the title of a webpage. Then when I reload the browser, I don't get the update on browser. So time it never updates even after many refresh, and sometime I get it after 30 seconds. I guess I am doing something wrong in my configuration. How you would setup the EmberJs with Docker for development
