Getting routing parameter values to the Backbone render function

I have a route set up like this:

var AppRouter = Backbone.Router.extend({
                routes: {
                    "items": "getItems", // matches http://example.com/#anything-here
                    "/*": "showAll",
                    "edit/:id" : "editItem",
                    "save/:id" : "saveItem",
                    "delete/:id" : "deleteItem"
                }
            });
            // Initiate the router
            var app_router = new AppRouter;

            app_router.on('route:getItems', function() {

            });

            app_router.on('route:showAll', function(){
                console.log("SHOWALL");
                 skillsview.render();
            });

            app_router.on('route:editItem', function(id){
                console.log("EDIT SKILL: "+id);
                editview.render(id);
            });

            app_router.on('route:saveItem', function(id){
                console.log("SAVED SKILL");
                skillsview.render(id);
            });
            app_router.on('route:deleteItem', function(id){
                console.log("DELETED SKILL");
                skillsview.render(id);
            });

However, I am getting a front end JS error when I try to send the id variable into my render function. The render function does not want to take any parameters I think. But if this is true, how can I send my router parameters to my render function where I fetch a Model using the id given from the router?
