Only one checkbox checked in repeater

I have a repeater with checkboxes for every item. I want to only have one checked at a time.

The checkboxes is asp:checkbox, don't know if it makes any difference. I tried with some jquery but it doesn't seem to work.

 <asp:Repeater runat="server" DataSourceID="SqlDataSource1" ID="repeater1">
  <ItemTemplate>
  <asp:CheckBox ID="CheckBox1" runat="server" OnCheckedChanged="CheckBox1_CheckedChanged" Checked='<%# Eval("carousel_check")%>'/>
 </ItemTemplate>
 </asp:Repeater>

I have tried to give the checkbox a cssclass (checked_button) and then this script.

    $(document).ready(function () {
        $('.checked_button').change(function () {
            if ($(this).is(':checked')) {
                $('.radio-similar').not(this).removeAttr('checked');
            };
        });
    });
