For binding textarea values you can use the change-function:

Template

{{textareaValue}}

Component

export class AppComponent implements OnInit {
  private textareaValue = '';
  doTextareaValueChange(ev) {
    try {
      this.textareaValue = ev.target.value;
    } catch(e) {
      console.info('could not set textarea-value');
    }
  }
}
