I would create a global mediator:

    export var mediator = _.extend({}, Backbone.Events);

And then use it to listen to messages in Views:

    m.mediator.on('change:page change:sort change:tags', this.renderTable, this);

And fire them from Models/Collections:

    m.mediator.trigger('change:sort', sortOrder);

Instead of listening to changes on them:

    this.paginator.bind('change', fn, this);

So I can plug & play different parts of the system together.
