If you want checkboxes to act as radio buttons, attach onClick event listeners to all checkboxes, remove "checked" attributes and place it on the one being clicked.

jQuery(checkboxes_controls).click(function(){
    jQuery(checkboxes_controls).removeAttr('checked');
    jQuery(this).attr('checked', 'checked');
});
