@kbowerma - this is a bit of a nit, but the deps should be in order 
1. native angular 
2. 3rd party
3. our custom

```
ChallengeFileUploadController.$inject = ['$document', '$log', '$scope', '$timeout',  '$upload', 'ChallengeService'];
```

```
function ChallengeFileUploadController($document, $log, $scope, $timeout, $upload, ChallengeService) {
```
