Ion-text-wrap doesn't work

Silly of me! I was using label in label

<ion-label class="ion-text-wrap">
  <ion-label [routerLink]="['/', 'posts', post.url]">{{post.title}}</ion-label>
</ion-label>

so i removed my extra label and css working just fine

  <ion-label class="ion-text-wrap" [routerLink]="['/', 'posts', post.url]">{{post.title}}</ion-label>

thanks guys
