ไม่สามารถรับค่าจาก textbox spinner หลังจากทีใส่ค่าเริ่มต้นด้วย dataset

<script type="text/javascript">
    $(document).ready(function() {
        $("#txtSpinThreshold").spinner({
            min: 0, max: 999, step: 1
        });
        $("#txtSpinDuration").spinner({
            min: 0, max: 999, step: 1
        });
        $("#txtSpinReset").spinner({
            min: 0, max: 999, step: 1
        });
        
    });
    </script>

<asp:TextBox ID="txtSpinThreshold" runat="server" MaxLength="3" Width="90px"></asp:TextBox>
<asp:TextBox ID="txtSpinDuration" runat="server" MaxLength="3" Width="90px" ></asp:TextBox>
<asp:TextBox ID="txtSpinReset" runat="server" MaxLength="3" Width="90px"></asp:TextBox>

        Dim Threshold As String = ds.Tables(0).Rows(0).Item("Threshold").ToString()
        Dim Reset As String = ds.Tables(0).Rows(0).Item("Reset").ToString()
        Dim Duration As String = ds.Tables(0).Rows(0).Item("Duration").ToString()
        txtSpinThreshold.Text = Threshold
        txtSpinReset.Text = Reset
        txtSpinDuration.Text = Duration
