Show data Binding WPF C #

Good day, I have had problems to show the data in a grid using wpf the code does not throw me error and reviewing the step by step I see that the methods take the values registered in the DB but do not take them to the grid. I share code:

1.View

        <DataGrid.Columns>
            <DataGridTextColumn Header="Inspección #" Binding="{Binding Path=numeroInspeccion}" Visibility="Visible" Width="*" IsReadOnly="False"/>
            <DataGridTextColumn Header="Vehiculo" Binding="{Binding Path=vehiculo}" Visibility="Visible" Width="*" IsReadOnly="False"/>
            <DataGridTextColumn Header="Conductor" Binding="{Binding Path=conductor}" Visibility="Visible" Width="*" IsReadOnly="False"/>
            <DataGridTextColumn Header="Fecha" Binding="{Binding Path=fecha}" Visibility="Visible" Width="*" IsReadOnly="False" />
            <DataGridTextColumn Header="Inspector" Binding="{Binding Path=inspector}" Visibility="Visible" Width="*" IsReadOnly="False"/>

        </DataGrid.Columns>
    </DataGrid>

2.Model

public DataTable CargarInspeccion()
        {


 DataTable dt = new DataTable("CargarInspeccion");
        SqlConnection SqlCon = new SqlConnection();

        try
        {
            SqlCon.ConnectionString = Conexion.Cn;
            //SqlCon.Open();

            //Código con sentencia
            SqlCommand sqlCmd = new SqlCommand();
            sqlCmd.Connection = SqlCon;
            sqlCmd.CommandText = "PRC_CARGAR_INSPECCION";
            sqlCmd.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter SqlDat = new SqlDataAdapter(sqlCmd);
            SqlDat.Fill(dt);
        }
        catch(Exception e)
        {
            dt = null;
        }
        return dt;
    }

3.Vista Modelo

private void CargarDatosInspeccion()
    {
        List<EstructuraDtg> obj = new List<EstructuraDtg>();

        foreach(DataRow dr in Operaciones.CargarInspecciones().Rows)
        {
            obj.Add(new EstructuraDtg { NumeroInspeccion = dr[0].ToString(), Vehiculo = dr[1].ToString(), Conductor = dr[2].ToString(), Fecha = dr[3].ToString(), Inspector = dr[4].ToString() });
        }

        this.DtInspeccion.ItemsSource = obj;
}
