No value accessor for ''

Ionic Framework ionic-v3

Hi folks! I’m getting the error No value accessor for '', anyone knows about it? Below is a code to reproduce the error:

import { Component } from '@angular/core'
import { Modal, NavController, ViewController, NavParams } from 'ionic-angular'

@Component({
  template: `
    <ion-list>
      <ion-item *ngFor="let item of items"
        (click)="openModal(item)"
      >{{item.name}}</ion-item>
    </ion-list>
  `
})
export class ModalTestPage {
  items: any
  constructor(private nav: NavController) {
    this.initializeItems()
  }

  initializeItems() {
    this.items = [
      {name: 'First item', data: [
        {id: '1', desc: 'Lorem'},
        {id: '2', desc: 'Ipsum'},
        {id: '3', desc: 'Dolor'}
      ]},
      {name: 'Second item', data: [
        {id: '1', desc: 'Lorem'},
        {id: '2', desc: 'Ipsum'},
        {id: '3', desc: 'Dolor'}
      ]},
      {name: 'Third item', data: [
        {id: '1', desc: 'Lorem'},
        {id: '2', desc: 'Ipsum'},
        {id: '3', desc: 'Dolor'}
      ]}
    ]
  }

  openModal(item) {
    let modal = Modal.create(ModalPage, {
      item: item
    })

    this.nav.present(modal)
  }
}


@Component({
  template: `
    <ion-list [(ngModel)]="options">
      <ion-item *ngFor="let i of item.data">
        <ion-label>{{i.desc}}</ion-label>
        <ion-checkbox [value]="i.id"></ion-checkbox>
      </ion-item>
    </ion-list>
  `
})
export class ModalPage {
  item: any
  options: any
  constructor(
    private nav: NavController,
    params: NavParams,
    private viewCtrl: ViewController
  ) {
    this.nav = nav
    this.item = params.get('item')
  }
}

Thaks!
