function list_add_radio_input(list,name) {
	var items = list.find('li');


	jQuery(items).each( function() {
		var item_id_attr = jQuery(this).attr('id');
		var id = item_id_attr.split('-')[1];
		var span_text = jQuery(this).find('span.text');
		var radio = jQuery('<input type="radio" name="'+name+'" value="'+id+'">');
		span_text.before(radio);
	});
}

##GIVES
<li id="item-7" class="">
<input type="radio" value="8" name="type"/>
<input type="radio" value="7" name="type"/>
</li>


##CHILDREN
function list_add_radio_input(list,name) {
	var items = list.find('li');


	jQuery(items).each( function() {
		var item_id_attr = jQuery(this).attr('id');
		var id = item_id_attr.split('-')[1];
		var span_text = jQuery(this).find('span.text');
		var radio = jQuery('<input type="radio" name="'+name+'" value="'+id+'">');
		span_text.before(radio);
	});
}
##WORKS but the var id for the children takes the value of the parent id...
example :
<li id="item-7" class="">
<input type="radio" value="8" name="type"/>
</li>
