$ scope不调用内部函数

Question

现在我们在调用DataService(Parse)的控制器中遇到一个问题,问题是这段代码不起作用:

    function MainCtrl($scope, DataService, $location)
{

    $scope.actionList = function() {

            // Call the service and fetch the list of signatures that match the given action ID
            DataService.getActions(function (results) {
                $scope.$apply(function () {
                    // Apply the results to the signatureList model so it will refresh the table in the view
                    $scope.actionList = results;
                });
            });

    };
}

我在DataService行中设置了一个断点,但它没有被击中,但是如果我以这种方式实现Ctrl它会接到调用并且它可以工作!!:

function MainCtrl($scope, DataService, $location)
{            

                // Call the service and fetch the list of signatures that match the given action ID
                DataService.getActions(function (results) {
                    $scope.$apply(function () {
                        // Apply the results to the signatureList model so it will refresh the table in the view
                        $scope.actionList = results;
                    });
                });          

    }

知道为什么会这样吗？

除了那个曾经工作(第二个实现)我想显示活动的属性,如果我试图得到这样的属性它不起作用:

<div id="wrapper"><div id="scroller">
<div ng-controller="MainCtrl">
    <ul id="thelist">
        <li ng-repeat="action in actionList">{{action.get('Action')}}</li>  
    </ul>
</div> 
</div></div>

但是,如果我试图获得像{{action}}这样的整个对象,我实际上可以看到所有条目.

将控制器更改为

function MainCtrl($scope, DataService, $location) {

    $scope.getActionList = function() {
        DataService.getActions(function(results) {
                    $scope.$apply(function() {
                                $scope.actionList = results;
                            });
                });

    };

    $scope.getActionList();
}

然后,如果你想重新加载actionList电话getActionList()
