I have a data bind in a form. Radio buttons bind to a select statement.

I have eveyrhting working in the bind, but I can't figure out one thing. The bind happens after someone clicks a radio button and then clicks somewhere else. I need it to happen immediately when someone clicks the radio button. I am guessing it is just a simple onChange commande, but I don't know what it is.

Code:
<cfparam name="get_skus.sku" default="79804">

<CFQUERY name="get_pricing" datasource="#mydatasource#" username="#myusername#" password="#mypassword#">
	Select * from productpricing where sku = <cfqueryparam value="#get_skus.sku#"> order by sortorder
</CFQUERY>
