UPDATED: Persist radio button selection in localStorage populates to all ng-repeat

I was able to get it working for a checkbox (radio button won't be long to solve), however, now it persists for all lessons because I'm using ng-repeat! Any help on how I can persist it for the selected lesson only? Thanks

code

$scope.yourprogress=window.localStorage.getItem('yourprogress') === 'false';
$scope.updateLocalStorage = function () {
window.localStorage.setItem('yourprogress', $scope.yourprogress);
console.log($scope.yourprogress);
};
