When repeating radio inputs, use this AngularJS directive to make the browser focus on the active input.

focusActiveDirective.js

angular.module('myApp', [])
  .directive('focusActive', function(){
    return {
      restrict: "A",
      link: function(scope, element, attrs) {
           	attrs.$observe('checked', function(){
           		if (element[0].checked){
		            element.focus();
		        }
           	})
      }
    }
  });

template.html

<!-- Use by calling focus-active as input attribute-->
<div ng-repeat="status in statuses">
{{status}}<input focus-active type="radio" ng-model="person.location" value="{{status}}">
</div>
