angularjs 动态加载JS问题

关于angularjs动态加载JS后之后，出现无法找到控制器的情况；

var sdApp = angular.module("sdApp", ["ngRoute", "oc.lazyLoad"]);

sdApp.config(function($routeProvider){
    var list = ["company/company", "test"];
    function href(b){
        var data = {
            resolve: {
                load: function($q, $ocLazyLoad){
                    var deferred = $q.defer();
                    var load = function(){
                        $ocLazyLoad.load("/theme/default/dist/scripts/"+b+".js");
                        deferred.resolve();
                    };
                    load();
                    return deferred.promise;
                }
            },
            controller: "companyCtrl",
            templateUrl: "/theme/default/dist/views/"+b+".html"
        };
        return $routeProvider.when("/"+b, data);
    };
    list.forEach(function(b){
        return href(b);
    });
});

Error: [ng:areq] http://errors.angularjs.org/1.5.7/ng/areq？p0=companyCtrl&p1=not%20aNaNunction%2C%20got%20undefined

请问有什么办法可以解决这种情况？
