  <pre><code>function IndexController($scope, $route, $routeParams, $location){
    $scope.sfv = project.version.name;
  }
  angular.module("TkwebMobile", ['ngRoute', 'ngCookies'])
    .controller('IndexController', ['$scope', '$route', '$routeParams', '$location', IndexController]);
  </code></pre>

  </code></pre>
  
  <p>Is it problem of grunt concat? (grunt-contrib-concat)</p>
