Angular2 - Radio Button Binding

Question

I want to use radio button in a form using Angular 2

Options : <br/>

1 : <input name="options" ng-control="options" type="radio" value="1"  [(ng-model)]="model.options" ><br/>

2 : <input name="options" ng-control="options" type="radio" value="2" [(ng-model)]="model.options" ><br/>

model.options initial value is 1

when the page is loaded the first radio button isn't checked and the modifications aren't binded to the model

Any Idea ?

Answer 1

use [value]="1" instead of value="1"

<input name="options" ng-control="options" type="radio" [value]="1"  [(ngModel)]="model.options" ><br/>

<input name="options" ng-control="options" type="radio" [value]="2" [(ngModel)]="model.options" ><br/>

Edit:

As suggested by thllbrg "For angular 2.1+ use [(ngModel)] instead of [(ng-model)] "
