CheckBox inside a DIV

I have a simple div that has 2 checkboxes inside. therefore when I select a checkbox inside the div I want to call a function and do something. ie.

<div id='wheels'>
    <asp:CheckBox ID="hotwheels" CssClass='WheelsCSS' Text="HOT" runat="server"/>
    <asp:CheckBox ID="Littlewheels" CssClass='WheelsCSS' Text="LITTLE" runat="server"/>
</div>

//Never gets fired but no syntax error I'm I missing something?
$('#wheels > input.checkbox').click(function () {
         //do something                
            });
