<label class="item item-radio">
<input type="radio" name="group" ng-model="user.answer" value="{{questions.quiz_ans_opt1}}">
<div class="item-content item-body">a) {{questions.quiz_ans_opt1}}</div><i class="radio-icon ion-checkmark"></i>
</label>
<label class="item item-radio item-body">
<input type="radio" name="group" ng-model="user.answer" value="{{questions.quiz_ans_opt2}}">
<div class="item-content item-body">b) {{questions.quiz_ans_opt2}}</div><i class="radio-icon ion-checkmark"></i>
</label>
<button class="button button-balanced button-block" ng-click="submitAnswer(user)">Submit</button>

Please have a look at this,
Try this,
In html,
<body ng-controller="MainCtrl">
<p>Hello {{name}}!</p>
<input type="radio" ng-model="user.answer" ng-value="'option a'">
<label>option a</label>
<br>
<input type="radio" ng-model="user.answer" ng-value="'option b'">
<label>option b</label>
<br>
<input type="radio" ng-model="user.answer" ng-value="'option c'">
<label>option c</label>
<br>
<input type="radio" ng-model="user.answer" ng-value="'option d'">
<label>option d</label>
<br>
<button ng-disabled="!user.answer" ng-click="submitAnswer(user)">Submit</button>
</body>
In app.js,
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.submitAnswer=function(user){
alert(user.answer);
}
});
Here is the plunker demo for the same
