AJAX checkbox

Question

I have a multi (7) column checkbox with form element attributes on my page:
onClick="refresh_reports_lov(this.value,this,$x('P507_SCHOOL'),$x('P507_YEAR'),'REFRESH_SIS_REPORTS_FILTER_LOV');toggle_items2(this.value,this)"
I am using Application process below to refresh the values, but when it fires it lists everything in 1 column and does not put in the 'On-Click'. How can you specify these things in the Application Process?
BEGIN
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<checkbox>');
FOR i IN (SELECT empno, ename
FROM emp
WHERE deptno = :selectlist_item_1
ORDER BY ename)
LOOP
HTP.prn ('<message>' || i.ename || '</message>');
HTP.prn ('<value>' || i.empno || '</value>');
END LOOP;
HTP.prn ('</checkbox>');
END;

I am using checkboxes in a report
SQL Query in Reports Region with checkboxes:
SELECT
APEX_ITEM.CHECKBOX(1,VALUE_FROM_TABLE,'checked="checked" onclick="javascript:f_ajaxAction(this);"')
FROM DUAL;
JavaScript Function in Regions Header that handles the Ajax Request and processes the Application Process:
<script type="text/javascript">
function f_ajaxAction( cb ){
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=AjaxApplicationProcess',0);
get.addParam('x01',cb.value); /*Parameter from Checkbox Value*/
gReturn = get.get();
get = null;
</script>
Application Process definition: AjaxApplicationProcess
declare
l_value varchar2(4000)
begin
-- checkbox value
l_value := wwv_flow.g_x01;
-- Do what you want with the value
END;
Maybe this helps you to use checkboxes with Ajax.
