我想弄清楚为什么我$watch没有被触发.这是相关控制器的片段:

$scope.$watch('tasks', function (newValue, oldValue) {
    //do some stuff
    //only enters here once
    //newValue and oldValue are equal at that point
});

$scope.tasks = tasksService.tasks();

$scope.addTask = function (taskCreationString) {
    tasksService.addTask(taskCreationString);//modifies tasks array
};

在我看来,tasks显然正在更新正确,因为我的长度限制如下:

<span>There are {{tasks.length}} total tasks</span>

我错过了什么？

我有一个看起来像这样的控件:

<telerik:RadCodeBlock runat="server">
    <script type="text/javascript">
        function refresh() {
            window.$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("RebindRecommendations");
        }
    </script>
</telerik:RadCodeBlock>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="AjaxRequest">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="NameOfGrid" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server" NavigateUrl="UrlOfPage" OnClientClose="refresh"></telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

页:

<script type="text/javascript">
    function closeWindow() {
        self.close();
        return false;
    }
</script>
<!-- form fields here -->
<telerik:RadButton runat="server" ID="_cancel" Text="Cancel" OnClientClick="closeWindow"></telerik:RadButton>
<telerik:RadButton runat="server" ID="_submit" Text="Submit" OnClientClick="closeWindow" OnClick="DoSomeDataBaseStuff"></telerik:RadButton>

这按预期工作.我的RadWindow被删除,我的控件的网格在点击取消或提交按钮时刷新.问题是数据库到那时还没有完成其工作,因此网格刷新不会显示更改.我试图将我的页面实现切换为如下所示:

页:

<script type="text/javascript">
    function closeWindow() {
        self.close();
        return false;
    }
</script>
