How to disable users from accessing previous page by browser back button after logout in angularjs application?

I have an angularjs web application. I am trying not to allow users to go to previous page using browser back button after logout. I wish to show users a messge like "Please login to continue". I am unable to get any ideas. Please suggest.

app.config(["$routeProvider", function($routeProvider) {
            return $routeProvider.when("/", {
                redirectTo: "/login"
            }).when("/dashboard", {
                templateUrl: "views/dashboard.html"
            }).when("/login", {
                templateUrl: "views/login.html"
            }).when("/pages/openAcc", {
                templateUrl: "views/pages/openAcc.html"
            }).when("/pages/docUpload", {
                templateUrl: "views/pages/docUpload.html"
            }).when("/pages/listview", {
                templateUrl: "views/pages/listview.html"
            }).otherwise({
                redirectTo: "/404"
            })
        }])    .run(function($rootScope, $location) {
                    $rootScope.$on("$routeChangeStart", function (event, next, current) {
                        if (!(next.templateUrl == "views/login.html")) {
                            $location.path("/login");
                        }
                    })
                })
