Directives have dependencies too, and you can use dependency injection to provide services for your directives to use.

Bad: If you want to use <alert> in another controller or page, you have to modify the AlertService. This might break things.

    <button ng-click="main.showAlert();">Something Failed</button>

</body>

</html>
angular.module("app", ["ui.bootstrap"])

    .controller('MainCtrl', function MainCtrl(AlertService) {

        var mainCtrl = this;

        mainCtrl.AlertService = AlertService;

    })

    .service('AlertService', function AlertService() {

        var AlertService = {};

        AlertService.false = true;

        AlertService.showAlert = function() {

            AlertService.alertType="success";

            AlertService.alertMessage = "There is a message";

            AlertService.isShowAlert = true;

        }

        return AlertService;

    });

Good: Using Directive injected by the service. Then the <alert> is no longer bind with the controller anymore.
