why shows cannot read property undefined?

In my ionic-Angular application,I have load the content from the db and successfully printed on console, but I cannot bind with view, it says app.html

  <ion-card-content>
  {{homeContent.about}}
  </ion-card-content>

component.ts

constructor(public navCtrl: NavController, navParams: NavParams, public 
   homeService: HomeContentService, 
  public loadingCtrl: LoadingController) {
 this.homeService.geteventHomeContentForPage(this.event.id).subscribe(data=>
 { 
  this.homeContent=data;

  console.log(this.homeContent) 
  console.log(this.homeContent.about) 

 })
}

My console
