                           <ion-list  *ngFor="let inner of item;let b = index;" radio-group [(ngModel)]="answers" name="answers" >
                                   <ion-label>{{b}} . {{inner[i][b].question}}</ion-label>
                                      <ion-item   *ngFor="let innermost of inner[i];let c = index;">
                                        <ion-label> {{innermost.answer}}</ion-label>
                                        <ion-radio  [value]="innermost.answer"></ion-radio>
                                      </ion-item>

                            </ion-list>
                    </div>

                <button ion-button type="submit">Submit</button>
    </form>

I want to make the model dynamic. Something like this in php:

echo '<input type="radio" name="salutation_description[]" value="'.$row1[0].'"/>'  

then pass to typescript.

Answer 1

removed [(ngModel)]="answers" name="answers" in this block of code and it works like a charm

  <ion-list  *ngFor="let inner of item;let b = index;" radio-group [(ngModel)]="answers" name="answers" >
