Stored procedure mapping using EF6 and Mysql database

Question

I have ac# application using Entity framework 6 and Mysql Database . I added this stored procedure:

DELIMITER $$
CREATE DEFINER=`root`@`localhost` PROCEDURE `ps_reservation`(IN id_compte varchar(128))

    if id_compte is null then

END$$
DELIMITER ;

When I added a new EF model, in the context I get this mappage:

 public virtual int ps_reservation(string id_compte)
{
    var id_compteParameter = id_compte != null ?
        new ObjectParameter("id_compte", id_compte) :
        new ObjectParameter("id_compte", typeof(string));

    return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction("ps_reservation", id_compteParameter);
}

I don't understand Why I get this method signature:

public virtual int ps_reservation(string id_compte)

I mean why the return type is integer !! Why it is not ObjectResult<ps_reservation_Result> ?

1. What are the reasons of this error?
2. How can I fix it?
