Redmine

We created a custom hook for issue status updates.
It works, but only when updating single issues.
When updating from the issue list by selecting multiple issues, then changing status via right click context menu, the hook is ignored.

It's implemented like this:

module MyContract
  class Hooks < Redmine::Hook::ViewListener
    def controller_issues_edit_before_save(context={})
      ...

What do I need to change in order to also have it listening for batch updates?
