Angular 2动态子表单验证问题

Question

当我想用动态子窗体保存我的更改时，我遇到了问题，它保留了我的旧值，我使用了formArrayName =＆＃34;＆＃34;对于父div和[formGroupName] =＆＃34; i＆＃34;对于孩子，包括formControlName =＆＃34; name＆＃34;对于特定的输入，但是当我想要保存它时保留旧的值。

该问题仅涉及动态部分，对于静态输入，一切都很有效，并保存数据。

它是我的代码：

 <div class="page-content">
  <button type="button" data-hover="tooltip" title="List" class="btn btn-orange" data-toggle="modal" (click)="backToList()">
  <button type="button" data-hover="tooltip" title="Save" class="btn btn-orange" data-toggle="modal" (click)="saveConfirm()">

  <form [formGroup]="formDatiCorrispettivi">
