ember member actions normalizing response

I am using ember member API actions and was wondering how can response be normalized in such cases.

I have a model "users" with member action "postAddress". It is a post request which returns me a response. Now the problem I am facing is data is not normalized as returned data does not map to any store model. I know when we do a findAll and give a model, then ember automatically normalizes the data returned from API call. But in case of member actions, can anyone suggest how can data be normalized? (snake case to camel case).
