Web api set Generic Class dynamically according the url

In the below code how to set generic 'T' as a class dynamically?

Currently am redirecting all the API request to a single web api called "dummy" by routing.

So url's like

"api/person" then take person as class 
"api/students" then take students as class

So here how to pass person or students or any other dynamic class in GenericDataController T.

     //web api controller 
      public class dummyController :GenericDataController<T> 
     {
        //
     }

GenericData web api

    public class GenericDataController<T> :ApiController where T : class
    {

    private IGenericDataService _dataService;
    public GenericDataController(IGenericDataService dataService)
    {
        _dataService = dataService;
    }

    // GET: api/GenericData
    public IEnumerable<T> Get()
    {

        return _dataService.Get<T>();
    }
   }

In my model i have all class models

  public class Person{
   //
   }
  public class Student{
   //
   }
