angular uigrid 的cell button click 事件無效

今天遇到個問題，我在angular UI-Grid 的列中加入了button, 可是ng-click事件無效，

後來在static overflow上面找到了答案：

原來：

$scope.gridOptions = {
  columnDefs = [
    { name: 'edit', displayName: 'Edit', cellTemplate: '<button ng-click="edit(row.entity)" >Edit</button>' }
  ],
  data: myData
};

$scope.edit = function( entity ) {
  ...some custom function using entity...
};

修改後：

$scope.gridScope = $scope;
$scope.gridOptions = {
  columnDefs = [
    { name: 'edit', displayName: 'Edit', cellTemplate: '<button ng-click="grid.appScope.edit(row.entity)" >Edit</button>' }
  ],
  data: myData
};

$scope.edit = function( entity ) {
  ...some custom function using entity...
};
