Page transitions with RequireJS and Backbone.js

I'm developing a mobile application using RequireJS and Backbone.js. I'd like to specify the transition from one page to another by adding data-transition and data-direction attributes to each anchor (in the same way as with jQuery Mobile):

<a href="#home" data-transition="slide" data-direction="left">Go to the home page</a>

All my views extend a base view that attaches a click handler to anchors and catches the values of these attributes:

define([
    'zepto',
    'lodash',
    'backbone'
], function ($, _, Backbone) {
    'use strict';

    BaseView = Backbone.View.extend({
        events: {
            'click a': 'navigate'
        },
        navigate: function (e) {
            e.preventDefault();

            var href = $(e.currentTarget).attr('href'),
                transition = $(e.currentTarget).attr('data-transition'),
                direction = $(e.currentTarget).attr('data-direction');

            Backbone.history.navigate(href, true);
        }
    });
});

My problem is that I don't know how to pass these values to the route handlers of my router, defined as another module:

define([
    'zepto',
    'lodash',
    'backbone'
], function ($, _, Backbone) {
    'use strict';

    var Router = Backbone.Thumb.Router.extend({
        routes: {
            '': 'home'
        }
    });

    var initialize = function () {
        var router = new Router();

        router.on('route:home', function () {
            require(['views/home'], function (HomeView) {
                var homeView = new HomeView();

                // Get the data-transition and data-direction attributes
                // ​​of the clicked anchor here:

                // var transition = ???,
                //     direction = ???;

                router.animate(homeView.render().$el, transition, direction);
            });
        });

        Backbone.history.
