Open new modal from a opened Modal with modal angularJS Bootstrap

I need to open a new modal from a opened modal. I try this in my modal controller to open the new modal.

$scope.ok = function () {

        var modalInstance2 = $modal.open({
            templateUrl: 'app/portal/modal/result/view/incidentResult.html',
            controller: 'incidentResult',
            resolve: { items: function () { return $scope.items; } }
        });
        modalInstance2.result.then(function (selectedItem) {
            $scope.selected = selectedItem;
        }, function () {
            $log.info('Modal dismissed at: ' + new Date());
        });
