我正在使用 Angular Formio 進行動態屏幕創建，作為其中的一部分，當我從數據庫獲取屏幕腳本時，如果我更改特定元素的標簽，我就可以ngOnInit()更改。但是一旦顯示屏幕，如果我更改標簽，它就不會生效。html<Formio [form]="form" [submission]="submission" (submit)="onSubmit($event)"></formio><div class="mb-5">    <div class="row">      <div class="col-12 mb-5">        <div class="pull-right" style="float:right;">          <button class="btn save-button" (click)="clearData()">Clear data</button>          <button class="btn save-button" (click)="showData()">Show data</button>        </div>      </div>    </div>  </div>成分ngOnInit() {    debugger;    this.triggerRefresh = new EventEmitter();    this.http.get('http://localhost:3000/angcomp/3')    .subscribe(      response  => {        debugger;        this.data = response.json();        this.form = this.data;        this.form.components[0].label = 'Changed';//it is updating the lable in view      },        err => {console.error(err)}    ); }showData() {    this.form.components[0].label = 'Again Changed'; // here it is not changing but in this.form.components[0].label value is displaying as 'Again Changed', but not effecting in front end}
