"Invalid column name" MVC

I have a table in a DbContext , I change its name, I update the database and when I run I am redirected to Visual Studio with the following error message:

  

Invalid column name 'SetorId'.

Note: The table name is Set_Id. I change the name in model and in the table itself before updating the database .

Model:

public class RamalModel
{
    public int ID { get; set; }

    [Required(ErrorMessage = "O nome é obrigatório.")]
    public string Nome { get; set; }

    [Required(ErrorMessage = "O número é obrigatório.")]
    public int Numero { get; set; }

    [ForeignKey("Setor")]
    public int SetorId { get; set; }

    public Setor Setor { get; set; }
}

DbContext:

public class RamaDb : DbContext
{
    public DbSet<Usuario> Usuarios { get; set; }

    public DbSet<RamalModel> Ramais { get; set; }

    public DbSet<Setor> Setores { get; set; }

    public DbSet<Area> Areas { get; set; }
}

Table:

   CREATE TABLE [dbo].[RamalModels] (
[ID]       INT            IDENTITY (1, 1) NOT NULL,
[Nome]     NVARCHAR (MAX) NOT NULL,
[Numero]   INT            NOT NULL,
[Setor_Id] INT            DEFAULT ((0)) NOT NULL,
CONSTRAINT [PK_dbo.RamalModels] PRIMARY KEY CLUSTERED ([ID] ASC)
);


GO
CREATE NONCLUSTERED INDEX [IX_SetorId]
ON [dbo].[RamalModels]([Setor_Id] ASC);
