Services details reload the same page instead to show the details

If you go to any of the services pages for example customers `http://opbeans-ruby:3000/customers` and you click on any customer you should go to the customer details
`http://opbeans-ruby:3000/customers/1` but instead reload the same page even do the URL changes. It happens the same with orders and products.

Steps to replicate:

* docker-compose build
* docker-compose up
* Go to `http://127.0.0.1:8000/customers` on a browser
* Click on any customer
* the same page is reloaded and this is wrong, it should load the customer details page.
