sign_in will not fetch the token

[mattSpell]

I'm using devise_token_auth with ng-token-auth and my user registration is working perfectly:

The sign_out works perfectly:

I try to login with the same email and password and it always returns 401:

Here is my registrations controller (which works great):

angular.module("angDomino").controller "UserRegistrationsCtrl", [
  '$scope'
  '$auth'
  ($scope, $auth) ->
    $scope.handleRegBtnClick = ->
      $auth.submitRegistration $scope.registrationForm
      return
    return
  ]

Here's my sessions controller which does not work:

angular.module('angDomino').controller 'UserSessionsCtrl', [
  '$scope'
  ($scope) ->
    $scope.$on 'auth:login-error', (ev, reason) ->
      $scope.error = reason.errors[0]
      return
    return
]

Anybody have any wisdom as to why this is? Any help would be greatly appreciated.
