Extend Ticket with prefilled organization serials


to extend the data models and databases via the zammad packages works fine. We want to have a serial dropdown in the ticket. We want to fill/sync the serials via REST to zammad, so a extra data model and controller makes sense, like the priorities.
The problem I have are that the coffeescript controllers, the *.erb ones are easy to debug and to extend. Now i searching for the integration point where i can place the serial number model. Or is there a better way to do this?
Do you have a hint where I can integrate the serialnumber field correctly? With the sync capabillity? What is the best environment to debug the coffeescript controllers and view models?

Thank you very much.
Best Regards
