Javascript 基于数组中值的ngChange更新禁用ngOptions

我正在尝试在已选择选项后，禁用选择中的选项。这取决于与以下代码中所示的每个“cusomter_no”关联的“perf_no”。ngChange在更新模型的同时更新关联对象中的“disabled”值。debounce的ngModelOptions对我不起作用是否有办法在ngChange完成后进行回调，以更新该对象的“disabled”值？或者是一个更好的方法来实现这一点？提前感谢

<div class="session-registrant-field field-dropdown">
      <label for="">{{nameLbl}}</label>
      <select
      ng-model="affiliateSelected[cartPerf.perf_no][$index]"
      ng-change="changedAffiliate(affiliateSelected, cartPerf.perf_no, $index, affiliateSelected[cartPerf.perf_no][$index].customer_no)" 
      ng-options="affiliate.fname + ' ' + affiliate.lname disable when affiliate.disabled for affiliate in affiliates | filter:cartPerf.perf_no | orderBy:affiliate.customer_no:true track by affiliate.customer_no"
      required>
        <option value="" disabled="">-- Select person --</option>
      </select>
    </div>

嗯，也许它不漂亮，但做它的工作（）：

这是基于这样一个事实，即changedAffiliate在被禁用后将额外运行1次
