在事件回调中更新模型时更新模型属性对视图没有影响,有什么想法可以解决这个问题吗？

这是我的服务:

angular.service('Channel', function() {        
    var channel = null; 

    return {        
        init: function(channelId, clientId) {
            var that = this;        

            channel = new goog.appengine.Channel(channelId);
            var socket = channel.open();

            socket.onmessage = function(msg) {
                var args = eval(msg.data);              
                that.publish(args[0], args[1]);
            };
        }       
    };
});

publish() 功能是在控制器中动态添加的.

控制器:

App.Controllers.ParticipantsController = function($xhr, $channel) {
    var self = this;

    self.participants = [];     

    // here publish function is added to service
    mediator.installTo($channel); 

    // subscribe was also added with publish        
    $channel.subscribe('+p', function(name) { 
        self.add(name);     
    });                 

    self.add = function(name) …

我想我在这里缺少一些简单(和重要)的东西.我正在使用一个包含模板的模板,该模板包含一个映射到某个值的输入:

<div ng-controller="Ctrl">
    <div ng-include src="'template.html'"></div>
</div>

<!-- template -->
<script type="text/ng-template" id="template.html">
    <input ng-model="testvalue" />
</script>

控制器:

function Ctrl($scope) {    
   $scope.testvalue= "initial value";
}?

警告$ scope.testvalue的值始终显示初始值,而不是更新的值(当您键入输入时).帮助我欧比万.你是我们唯一的希望.
