我试了一下ng-model，但是没效果，问题在哪？代码如下：
script:

       $scope.allMsgType=[                    
            {id:"11",name:"输入内容"},
            {id:"12",name:"连接h5"},
            {id:"13",name:"无详情"}
        ];
        $scope.msgTypeDefault=$scope.allMsgType[0];

html

       <span ng-repeat="x in allMsgType">
            <label ng-click="events.getMsgTypeData(x.id)">
                <input  name="msgType" type="radio" ng-model="msgTypeDefault">
                <span>{{x.name}}</span>
            </label>
        </span>
