This won't update right until https://codereview.chromium.org/526633002/ lands
since you don't clear the old alerts. Might want to rebase your patch on top of
that one.

These two requests should be done in parallel. You can use Promise.all to
execute code once they've both loaded.

Use Object.keys http://sugarjs.com/api/Object/keys. You can find other example
around the code that do this.

[shans, 2014/09/04 01:59:42]

Don't store the raw data object we get from the server. Instead, use a model
class so that the things exposed are clearly documented and so there's a place
to attach related code. In this case, if you do the CTTrooperFailureGroupData
thing, then you could expose the fields you want on that.

[shans, 2014/09/04 01:59:42]

Done.
