Alert directive not showing after it has been rendered once

I have a directive to display an alert message every time a post call succeeds/fails. The alert for the first post always succeeds but if I close the alert, and trigger another post the alerts don't show anymore.

Some code below:

Include tag in html

<alert message="notification"></alert>

Directive 

app.directive("alert", function(){
        return{
            restrict: 'EA',
            templateUrl: "alert.html",
            replace: false,
            transclude: false,
            scope: {
                message: "=",
                close: "&"
            },
            link: function(){

            }
        };
    });

Template

<div class="alert alert-{{message.type}}" ng-show="message.text">
    <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>
    <div>{{message.text}}</div>
</div>

UPDATE: http://plnkr.co/edit/mECmQNSgW0EdXZGPmkNx?p=preview

Any thoughts?

Thanks in advance.

Per the Bootstrap documentation (emphasis mine):

… Closing an alert removes it from the DOM.

Because it's removed from the DOM it will not show up again...

Instead of using data-dismiss="alert" you can have your close button call the close function. The close function can then clear the notifications since you have $scope.notification in the isolated scope as scope.message:

var app = angular.module('app', []);

app.controller('AlertDemoCtrl', function($scope) {
  $scope.notification = {};

  $scope.alertNotif = function() {
    $scope.notification.type = "error";
    $scope.notification.text = "demo text";
  };
});


app.directive("alert", function() {
  return {
    restrict: 'EA',
    template: '<div class="alert alert-{{message.type}}" ng-show="message.text">' +
      '<button type="button" class="close" ng-click="close()" aria-hidden="true">&times;</button>' +
      '<div>{{message.text}}</div>' +
      '</div>',
    replace: false,
    transclude: false,
    scope: {
      message: "=",
      close: "&"
    },
    link: function(scope) {
      scope.close = function() {
        scope.message = {};
      }
    }
  };
});
