Answer 1

What about :

<form name="articleForm" class="form-horizontal" ng-submit="submit()" novalidate>

and then have something like this in your controller :

$scope.isNewUser = typeof $scope.user.id === 'undefined';

function create() {...}
function update() {...}

$scope.submit = function () {
    $scope.isNewUser ? create() : update();
}
