JuiceUI Slider - ValueChanged event not firing
===

I'm trying to include a JuiceUI Slider control inside a ASP.NET GridView control where each row will have a unique slider control. As a test I created a Slider control:

    <juice:slider ID="MasterThresholdSlider" Value="50" Min="0" Max="100" runat="server"
    Step="25" ValueChanged="MasterThresholdSlider_ValueChanged"></juice:slider>
    <asp:TextBox ID="MasterThresholdText" runat="server"></asp:TextBox>   

Now from the documentation I have read, I can detect the value being changed when the ValueChanged event is raised. So in the code behind I have created the following:

   

    protected void MasterThresholdSlider_ValueChanged(object sender, EventArgs e)
    {
       Juice.Slider slider = (Juice.Slider)sender;

       MasterThresholdText.Text = slider.Value.ToString();
    }

For some reason the event doesn't fire when I run the application (breakpoint is at the beginning of the event). Anyone know what I'm doing wrong?
