AngularJS ng-model data from radio button

Question

I have a short form in AngularJS . I use ng-repeat to show genders and validate their radio buttons The problem is that I want to get the value of the radio button selected and print this out using ng-model. How can achieve this?

The problem is you're binding selected gender, a primitive value, to your $scope. When you use ng-repeat it creates a new scope and inherits the values from it's parent. Unfortunately, because your values are primitive (a number), they are passed by value instead of reference, so you only get one way binding. This is why it's always recommended to store values on an object in scope instead of directly.

Here's a link to a working controller: http://plnkr.co/edit/Y7sTEaYMx0aD4fPDHAMA?p=preview

I added this, and adjusted the rest of the code accordingly:

$scope.user = {
    selectedGender: 'none'
}
