Microsoft JScript runtime error: '' is undefined, client on-load event

[Phil]

Hi:

I am getting:
  Microsoft JScript runtime error: 'onLoadAmount' is undefined
error. 

<telerik:RadNumericTextBox ID="overAmountTextBox" Runat="server" MaxLength="13"
    MaxValue="999999.999999" MinValue="-999999.999999" Text='<%# Bind("overAmount") %>'
    TabIndex="7">
    <ClientEvents OnLoad="onLoadAmount" />
    <FocusedStyle HorizontalAlign="Right" />
    <EnabledStyle HorizontalAlign="Right" />
    <NumberFormat DecimalDigits="4" />
</telerik:RadNumericTextBox>

<script type="text/javascript">
    //<![CDATA[
    //
    function onLoadAmount(sender, args) {
        alert('Amount');
    }
    //]]>
</script>

The RadNumericTextBox is in a FormView control, when I get the error.  If I extract the code and place it on a simple page it finds the on load event.
