  <pre><code>&lt;input type="text" ng-model="somethingHere2"/&gt;
  Select:

          ng-model="somethingHere2" 
          ng-options="items for items in options.values"&gt;
  &lt;/select&gt;
  
  $scope.workItem = 100;
  $scope.options = {
    default:$scope.workItem,
    values:[1,2,3,4,5]
  };
  $scope.serviceValues = Service; // Service = .factory('Service',...)
