angular.js - ionic工程中$scope.$watch监听不到input的值

Question

ion-content标签下的input变化$scope.$watch是监听听不到的

<ion-view>
    <ion-content>
        <input type="text" ng-model='myNumber' />
        {{myNumber}}
    </ion-content>
</ion-view>

要这样才行

<ion-view>
    <input type="text" ng-model='myNumber' />
    {{myNumber}}
</ion-view>

请问这是因为什么呢？
