Upgrade existing Site Column in SharePoint-hosted app

My Szenario:

I have a SharePoint-hosted app with several Lists, Content Types and Site Columns. Now I would like to add some new choices to an existing Site Column (Choice Field).

The Problem:

When upgrading the app, only the Site Column and the Site Content Types are updated. The List Content Types and the List Columns still have the old choices.

The questions:

  • Is there a declarative way to push down the changes to the List instances?

  • Is there a mechanism to catch the upgrade event to inject custom CSOM code?
