How to fill a datagridView with my stored procedure on load

Question

I have this stored procedure that selects the top 10 results from its inner join

CREATE PROCEDURE SP_SELECT_DOCS_WHERE_JOBID_STATUS
    @JobID INT,
    @BatchID INT
AS
BEGIN
    SELECT top(10) i.*
    FROM jobtable AS j
    INNER JOIN batchtable AS b ON j.JobID = b.JobID
    INNER JOIN imgtable AS i ON i.BatchID = b.BatchID
END

What I don´t know why it's not working is when I run the app the datagrid is just empty.

This next code is on my dataAccess class

public DataTable SP_SELECT_DOCS_WHERE_JOBID_STATUS_IBML1(int JobID, int BatchID)
{
        try
        {
            ManageConnectionStateIbml1();
            SqlCommand command = new 
            SqlCommand("SP_SELECT_DOCS_WHERE_JOBID_STATUS", connectionIBML1);
            command.CommandType = CommandType.StoredProcedure;
            command.Parameters.AddWithValue("@JobId", JobID);
            command.Parameters.AddWithValue("@BatchId", BatchID);
            SqlDataAdapter adapter = new SqlDataAdapter(command);
            DataSet ds = new DataSet();
            adapter.Fill(ds);

            return ds.Tables[0];
        }
        catch (Exception ex)
        {
            throw ex;
        }
        finally
        {
            ManageConnectionStateIbml1();
            connectionIBML1.Close();
        }
}

And finally there is my Form file that I am trying to fill the dgv

private void FillDGVDocs(int JobID, int BatchID)
{
        dataGridViewDocumentos.DataSource = null;
        dataGridViewDocumentos.Columns.Clear();
        dataGridViewDocumentos.Refresh();

        DataTable dt = da.SP_SELECT_DOCS_WHERE_JOBID_STATUS_IBML1 (JobID, BatchID);
        dataGridViewDocumentos.DataSource = dt;

        dataGridViewDocumentos.Columns[1].HeaderText = "Caixa";
        dataGridViewDocumentos.Columns[2].HeaderText = "DOC";
        dataGridViewDocumentos.Columns[3].HeaderText = "ID";
        dataGridViewDocumentos.Columns[4].HeaderText = "PROC";
}

Thanks in advance guys.
