title: Update value in select depending from other field in Angular 8
body: <p>I'm trying to update the value in select in Angular 8.
  I found that I can use:</p>
  
  <pre><code>$('#selectSeccion').val("SeccionOption");
  </code></pre>
  
  <p>This select is the next one:</p>
  
  <pre><code>&lt;select name="seccion" class="form-control" id = "selectSeccion"&gt;
     &lt;option *ngFor="let seccion of seccion" [ngValue]="seccion"&gt;{{seccion.seccion}}&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>jQuery code is not working when I use the select with Angular, only works when select is normal html like the next one:</p>
  
  <pre><code>&lt;select class="form-control" id = "prueba"&gt;
      &lt;option value = ""&gt;&lt;/option&gt;
      &lt;option value = "other"&gt;other&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>How can I update the value on the "ng" select?</p>
