Варианты инициализации views в backbone
=======================================

* в рельсовой вьюхе
* через jQuery селекторы (если есть id, инициализируем нужные вьюхи)
* через gon передавать контроллер и экшен
* написать роутер, основанный на window.location(придется отказаться от single page)

для всех, кроме последнего:
 * инициализировать вьюхи
