This was brought up in my Angular-Slickgrid repo and is now supported. I am assuming we can also do this in this repo.

Some references

• issue #20 on the Angular-Slickgrid repo
  • a few notes and test cases are shown in there
• in that repo, there's a Getter on columnDefinitions which will trigger a translateHeader() if the Column Definitions changes, see here and here
  • we probably need to do the same in Aurelia

Reference PR #55 this PR is what will make this possible.
