Current behavior:

When I bind ion-radio (inside ion-list radio-group) to object, only first item is selected and ngModel value is not the binded object.

When I bind ion-option (inside ion-select) to object, all options are selected when I select someone and ngModel value is not the binded object.

Expected behavior:
When I bind ion-radio (inside ion-list radio-group) to object, I expect that I can select any item (not only the first) and ngModel value will be changed to the selected radio value binded to object.

When I bind ion-option (inside ion-select) to object, I expect that only one ion-option will be selected and ngModel value will be changed to the selected option value binded to object.

Steps to reproduce:

Here is http://plnkr.co/edit/0ZywzZGIVYV0eQcRy7A8?p=preview example. If you try to select Test2 item with radio you cannot do it and you will see strange output for the radio variable value. If you try to select some item with select, you will see that all options are selected.

Related code:

<h2>ion-list tradio-group [(ngModel)]="radio"</h2>
  <ion-list radio-group [(ngModel)]="radio">
    <ion-item *ngFor="let i of items">
      <ion-label>{{i | json}}</ion-label>
      <ion-radio value="{{i}}"></ion-radio>
    </ion-item>
  </ion-list>
  Here is the radio value: {{(radio||{}) | json}}

  <h2>ion-select [(ngModel)]="select"</h2>
  <ion-list>
    <ion-item>
      <ion-label>Select</ion-label>
      <ion-select [(ngModel)]="select"> 
        <ion-option *ngFor="let i of items" value="{{i}}">{{i|json}}</ion-option>
      </ion-select>
    </ion-item>
  </ion-list>
  Here is the select value: {{(select||{}) | json}}

where radio, select, items define in the HomePage:
export class HomePage {

  appName = 'Ionic App';
  radio: any;
  select: any;
  items: any;

  constructor(private navController: NavController) { 
            this.items = [
      { value: 1, name: "Test1" },
      { value: 2, name: "Test2" }
    ]
  }

}

Hmm it seems to be an issue with interpolation. Can you use property binding: http://plnkr.co/edit/oP271SgvnY6ljnwLxBBY?p=preview

<ion-radio [value]="i"></ion-radio>
