Default Updating Database from Dataset

I have a class that creates a dataset and dataadapter.
When the user updates a Windows form, I want the dataadapter to update the DB of course. The code runs without an error , but the database does not get updated.
here is where the Dataadapter is created:
Code:
        Me.EmployeeDA = New SqlDataAdapter("SelectedEmployee",
connection)
        'Dim SELECTED As New DataSet
        With EmployeeDA
            .TableMappings.Add("Employees", "SelectedEmployee")
            .MissingSchemaAction = MissingSchemaAction.AddWithKey
            .SelectCommand.CommandType = CommandType.StoredProcedure
            .SelectCommand.Parameters.Add("@LastName", empLname)
            .SelectCommand.Parameters.Add("@FirstName", empFname)
            .FillSchema(SELECTED, SchemaType.Source)
            .Fill(SELECTED) 
        End With
no errors there and the dataset gets filled with exactly one row as it should.

Ok, edit the current data in the dataset

Code:
        Dim drCurrent As DataRow
        drCurrent = oEmployee.SELECTED.Tables(0).Rows.Find(empID)
        drCurrent.BeginEdit()
        drCurrent("Title") = oEmployee.Title
        drcurrent.EndEdit()
OK , send the changes back to the Database

Code:

        oEmployee.EmployeeDA.Update(oEmployee.SELECTED)
this all runs without error, but the database does not update.
is this code correct, or am i missing something?
