Not display inside ion-item

[hemnath11]

<ion-list>
  <ion-item>
    <rating [(ngModel)]="rate" 
        readOnly="false" 
        max="5" 
        emptyStarIconName="star-outline" 
        halfStarIconName="star-half" 
        starIconName="star" 
        nullable="false"
        (ngModelChange)="onModelChange($event)"> 
    </rating>
  </ion-item>
</ion-list>

Any help?

Make sure that "rate" variable and "onModelChange" function exist (in most cases there is no need to declare "ngModelChange").
