Javascript 具有隔离作用域的内部指令的角度形式

我有一张这样的表格

<ng-form name="investorQuestionaireForm" ng-show="user && user.investorType">
    <input 
        type="radio" 
        required
        name="recesso" 
        ng-model="investorQuestionaire.recesso" 
        ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/> 
    <input 
        type="radio" 
        required
        name="recesso" 
        ng-model="investorQuestionaire.recesso"
        ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/>
</ng-form>

我面临的问题是，当我单击单选按钮时，

investorQuestionaire.recesso

的值没有更新，没有触发

ng change

函数，而且大多数

单选按钮仍然是原始的（在html类和指令范围中）。我认为数据绑定存在一些问题

关于此行为的可能错误有何建议？
您的单选按钮似乎没有值

向单选按钮添加一些值，然后重试。比如说

<ng-form name="investorQuestionaireForm" ng-show="user && user.investorType">
<input 
    type="radio" 
    required
    value="option1"
    name="recesso" 
    ng-model="investorQuestionaire.recesso" 
    ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/> 
<input 
    type="radio" 
    required
    value="option2"
    name="recesso" 
    ng-model="investorQuestionaire.recesso"
    ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/>
</ng-form>



<ng-form name="investorQuestionaireForm" ng-show="user && user.investorType">
<input 
    type="radio" 
    required
    value="option1"
    name="recesso" 
    ng-model="investorQuestionaire.recesso" 
    ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/> 
<input 
    type="radio" 
    required
    value="option2"
    name="recesso" 
    ng-model="investorQuestionaire.recesso"
    ng-change="investorQuestionaireValidation('recesso', investorQuestionaireForm)"/>
</ng-form>
