Answer №1

Your Plnkr appears satisfactory, however it is recommended to utilize:

$scope.tasks.push({
    "taskName" : $scope.taskName,
    "priority": $scope.selectedP
});

in place of an extra [].

Answer №2

Take a look at this function:

$scope.AddTask = function() {
  $scope.tasks.push({
    "taskName": $scope.taskName,
    "priorty": $scope.selectedP
  });
};

Make sure to remove the [] before the {} in $scope.tasks.push. Instead of pushing another array, they should be pushing an object into $scope.tasks.
