Backbone.js - Dynamic routing for a large site

I am planning to use backbone + require for an application which has more than 30 modules. Instead of creating separate route for each module, I am planning to create something like this.

Not sure it this is a best practice. Please guide.

routes: {
  ":module"                   : "routeLevelOne",
  ":module/:id"               : "routeLevelTwo",
},

routeLevelOne: function(module){
    require(['views/' + module + 'View',],
        function(){
          require('views/' + module + 'View').render();  
       }
    );
},

routeLevelTwo: function(module, id){
    require(['views/' + module + 'View',],
        function(){
          require('views/' + module + 'View').renderWithId(id);  
       }
    );
},
