I have some inputs (Checkboxes) and I want them to be disabled if my Booleans are true.
But its not working... The funny thing is the submit button works just fine and thats the same method...

myComponent.html
```lang-c#
          &lt;form [formGroup]=&quot;BetreuungsoptionForm&quot; (ngSubmit)=&quot;onSubmit()&quot;&gt;
            &lt;label *ngIf=&quot;!eingetragen&quot; for=&quot;art&quot;&gt;Art&lt;/label&gt;
            &lt;select *ngIf=&quot;!eingetragen&quot; formControlName=&quot;art&quot; id=&quot;art&quot; class=&quot;form-control&quot; [(ngModel)]=&quot;Art&quot; required &gt;
              &lt;option value=&quot;festeAnmeldung&quot;&gt;feste Anmeldung&lt;/option&gt;
              &lt;option value=&quot;flexibleAnmeldung&quot;&gt;flexible Anmeldung&lt;/option&gt;
            &lt;/select&gt;
            &lt;label for=&quot;datum&quot;&gt;Beginn Datum&lt;/label&gt;
            &lt;input formControlName=&quot;datum&quot; type=&quot;date&quot; id=&quot;datum&quot; class=&quot;form-control&quot; required&gt;
            &lt;label *ngIf=&quot;(Art == &#39;festeAnmeldung&#39;)&quot; for=&quot;montag&quot;&gt;Montag&lt;/label&gt;
