ng-model
<script> angular.module('radioExample', []) .controller('ExampleController', ['$scope', function($scope) { $scope.color = { name: 'blue' }; $scope.specialValue = { "id": "12345", "value": "green" }; }]); </script> <form name="myForm" ng-controller="ExampleController"> <label> <input type="radio" ng-model="color.name" value="red"> Red </label><br/> <label> <input type="radio" ng-model="color.name" ng-value="specialValue"> Green </label><br/> <label> <input type="radio" ng-model="color.name" value="blue"> Blue </label><br/> <tt>color = {{color.name | json}}</tt><br/> </form> Note that `ng-value="specialValue"` sets radio item's value to be the value of `$scope.specialValue`.
