Try:

<my-tabs>
  <my-tab [tabTitle]="'Tab 1'">
    <form [formGroup]="MyGroup">
      <div formGroupName="averageMos">
        <input type="text" formControlName="critical">
      </div>
    </form>
  </my-tab>
  <my-tab tabTitle="Tab 2">
    Tab 2 content
  </my-tab>

</my-tabs>

Please note that I have used formGroupName and not FormGroupName in html.

Here is the working demo
