Backbone router events

Question

Does in Backbone.Router exists the events both before and after performing routing? My app works with jQuery.mobile and call to $.mobile.changePage was needed before route was performed and in controller have access to currently showing page by $.activePage. When action of controller is done, I should trigger the create event on document to get 'enhanced' by $.mobile newly created elements. I did this by replacing loadUrl

Backbone.history.loadUrl = ( function( old  ){
    return function() {  
       Router.trigger("all:before");   
       old.apply( Backbone.history, arguments );
       Router.trigger("all:after" );
    }
})( Backbone.history.loadUrl  );



 //Router.initialize
 initialize: function() {
     this.bind( "all:before", function( ) {  
         $.mobile.changePage( window.location.hash.split( "/" )[0] || "home", { changeHash:false} );
     });

     this.bind( "all:after", function() {
       $.mobile.activePage.trigger('create'); 
     });  
  }

Is there maybe some built-in events like this?
