Ionic 3 - modal backdrop does not work

Question

I want my modal pops up (with backdrop) rather than a new page. I followed some tutorials but the backdrop is not working (it should be activated by default). I am sure I am missing something.

Here the code from the page where the modal is opened.

openPhonesModal(){
const myModalOptions: ModalOptions = {
  showBackdrop: true,
  enableBackdropDismiss: false
};
const myModalData = {
phone1: '01 239 239',
phone2: '901 200 438'
};
const myModal: Modal = this.modal.create('ModalseephonesPage',{phones: 
myModalData},myModalOptions);
myModal.present();
}

Here the code of the modal itself:

export class ModalseephonesPage {
constructor(private navParams: NavParams, private view: ViewController) {
}
ionViewWillLoad() {
const phones = this.navParams.get(‘phones’);
console.log(phones);
} 
closeModal(){
this.view.dismiss();
}
}

I hope I provided enough information. Thank you in advance.
