Pass NodeJS function to an Angular Directive.

I am currently trying to display a error message if a user inputs a wrong username or password. The tricky part is that I am not using EJS or Handlebars, or any kind of template engine but raw HTML with Bootstrap.

I saw one other good question Good Similar Question of how to pass values from Nodejs to Angular. Sadly this didn't seem to help.

Here is my NodeJS + Passport User Authentication function:

 function isLoggedIn(req, res, next) {
        console.log('here is Authenticated', req.isAuthenticated());
        if (req.isAuthenticated()){
           return next();
        }else{
           res.json({"message": "Failed login. Wrong Username or Password"});
            res.redirect('/login');
            console.log("NO PERMISSION HAS BEEN GIVEN");
        }
    }

So my Idea was to send the message as an JSON object and get it with Angular:

 var app = angular.module('myApp', []);
        app.controller('myCtrl', function($scope, $http) {

            $http.get("/login").then(function(data){
                $scope.message = data;
                    console.log("message loaded" + data);
                });            
            });

and of course I am trying to display the message with .

Sadly this method is not working, I am trying a second way which involves using ng-show.

Can I pass a NodeJS function to a ng-show? Something similar to:

<div class="alert alert-danger" ng-show="isAuthenticated = true">
                 <p> Failed login message </p>
</div>

If not, how can I display a failed login message to a static html file without using jade, handlebars or any other template engine?
