angular-google-maps控制器功能未触发

Question

我正在尝试让这个地图库正常工作......它似乎已经正确设置但我无法让它运行。这是带控制器的plunkr。 getOffices不会触发

 <form ng-submit="getOffices()">
  <input type="submit" id="submit" value="Show Map" />
 </form>

 $scope.getOffices = function () {
  alert('1');
  try{
     alert('2');
     var tmp = mapDataFactory.query();
       alert('data: ' + tmp[0]);

    $scope.GlobalOffices =  $.grep(tmp, function (e) {
          if (e.locationType === "HEADQUARTERS") {
               e.markerIcon = $scope.map.icon.Headquarters;
          }
          else {
               e.markerIcon = $scope.map.icon.Branch;
           }
           return true;
         });
  }
  catch(e){
     alert('e: ' + e);
  }
}
