Succeeding CFSELECT not binding correctly

I've searched the web, and a number of awesome tutorials, but I keep getting stuck on my bind failing, but I can't figure out why! I am using the name of the preceeding cfselect for the current method argument, I've checked that both cfselects work correctly when the second does not depend on the first. It looks like the binding happens AFTER the error, which I'm not sure how to fix. And it also looks like it's binding to all the data returned from the first cfselect call, instead of just the default selected id. If anyone can show me the error of my ways, I'd very much appreciate it!

[code]
.cfm
<cfselect name="type_id" bind="cfc:calls.call_types()" bindOnLoad="true" />
<cfselect name="concern_id" bind="cfc:calls.get_concerns({type_id})" />
