带对象数据源的ng-options

我很难理解ng-options如何与数据源一起工作.我已经阅读了文档,我觉得我正在完成所需的工作,但在尝试时仍然会遇到问题.

<!DOCTYPE html>
<html ng-app="app">
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js">              </script>
    <link rel="stylesheet" href="style.css" />
    <script type="text/javascript">
      angular.module('app', [])
      .controller('IndexCtrl', ['$scope', function($scope) {
        $scope.types = {
          1: "value1",
          2: "value2",
          5: "value3"
        };
      }]);
    </script>
  </head>
  <body ng-controller="IndexCtrl">
    <select ng-model="type" ng-options="k as v for(k, v) in types">
      <option value="">Select Type</option>
    </select>
  </body>
</html>
