Tips for efficiently loading javascript between pages while utilizing the $routeProvider feature in Angular1

Currently, I am using Angular's $routeProvider and $locationProvider to navigate through an SPA. I am having difficulty figuring out how to apply JavaScript functionality across different pages using a controller. Whenever I switch pages, the JavaScript controller does not seem to run as expected. Below is an example that showcases this issue. The script is referenced from mainScript.js

app.config(['$routeProvider', '$locationProvider', function ($routeProvider, 
$locationProvider) {
    $locationProvider.html5Mode(true);
    $routeProvider.when("/", {
            templateUrl: "partials/home.html"
            , controller: "PageCtrl"
        })
        // Pages
        .when("/pricing", {
            templateUrl: "partials/pricing.html"
            , controller: "PageCtrl"
        })
        .otherwise("/404", {
            templateUrl: "partials/404.html"
            , controller: "PageCtrl"
        });
  }]);

 app.controller('PageCtrl', function ( $scope ) {

 $scope.menuCtrl = function(){
        // Implement code to be executed across pages
    }
    $scope.menuCtrl();

});
}());

To use lazy loading, simply inject oclazyload. First, inject oc.lazyload into your app like this:

app.config(['$routeProvider', '$locationProvider', function ($routeProvider,
    $locationProvider) {
        $locationProvider.html5Mode(true);
        $routeProvider.when("/", {
            templateUrl: "partials/home.html",
            controller: "PageCtrl",
            resolve:{
                loadFiles: [
                    "$ocLazyLoad", function ($ocLazyLoad) {
                        return $ocLazyLoad.load([
                            "mainScript.js"
                        ]);
                    }
                ]
            }
        });
    }])
