How to use ASP.NET MVC Generic Controller to populate right model

Question

I asked a question about ASP.NET MVC Generic Controller and this answer shows a controller like this:

public abstract class GenericController<

You may create a set of repositories for working with your entities, like CustomerRepository, ProductRepository from base interface like

public interface IBaseRepository
{
  T Get(int id);
  void Save(T entity);
}

and then extend your base controller class with repository type and its instance with any of DI frameworks

public abstract class GenericController 
        where T : class
        where TRepo : IBaseRepository, new()
    {
        private IBaseRepository repository;

        public GenericController() 
        {
            repository = new TRepo();
        }

        public virtual ActionResult Details(int id)
        {
           var model =repository.Get(id);
           return View(model);
        }
    }

Example for CustomerController

public class CustomerController : GenericController
{

}

where CustomerRepository:

public class CustomerRepository : IBaseRepository
{
  public T Get (int id) 
  {
    // load data from DB
    return new Customer();
  }
}
