<select [(ngModel)]="profile.type" name="type"(change)="selectPhoneType($event,mailCreate,'phone4_Value')">
                        <option value="">Select type</option>
                        <option *ngFor="let types of mobiletypes" [ngValue]="types.value">
                          {{types.value}}
                        </option>
                        <option value="addMore">Add More</option>
                      </select>
                    </div>

i have this dropdown when i change the dropdown value it should automatically select the

 selectPhoneType(event,mailCreate,type)
  {
    this.activeType=type;
    event.preventDefault();
    let value = event.target.value;
    if(value=='addMore')
      {
        this.addMailCreateLabel(mailCreate);
        this.profile.type='';
      }
  }

first value but in my case it is not selecting first value after addMore is selected.
