Dynamic Action on DOM object not working

Question

Thru a dynamic action I am executing PL/SQL Code that creates additional item using APEX_ITEM.CHECKBOX (see code on bottom). Thru another Dynamic action, I am trying to execute additional Java. I have it set to fire like this:
Event: Click
Type: DOM Object
DOM Object: document.forms[0].f11 (this matches the APEX_ITEM.checkbox fxx value)
Just trying a simple alert("hi"). doesn't work. Am I missing something?
DECLARE
l_hold_table_name varchar2(1000) := :P1223_HOLD_TABLE_NAME;
l_hold_html varchar2(32000) := '';
l_hold_session_state varchar2(32000) := '';
CURSOR get_columns IS
select b.column_heading, b.column_name
from dual
BEGIN
l_hold_html := '<DIV><TABLE border="2"><THEAD><TR><TH>' || l_hold_table_name ||
'</TH></TR></THEAD>';
FOR x in get_columns LOOP
l_hold_html := l_hold_html || '<TR><TD>' || APEX_ITEM.CHECKBOX(20,x.column_name,null) || x.column_heading || '</TD></TR>';
END LOOP;
l_hold_html := l_hold_html || '</TABLE><DIV>';
:P1223_HOLD_INNERHTML := l_hold_html;
END;

Hi,
first your code in example does not compile.
CURSOR get_columns IS
select b.column_heading, b.column_name
from dual
There is a ; missing and even with that this query is not OK.
If you have a problem with DOM selector, then try jquery selector:
Event:Click
Selection Type: jQuery Selector
jQuery Selector: input:checkbox[name*='f11']
For testing I created a test page with one dynamic PLSQL region and following source:
DECLARE
  l_hold_table_name varchar2(1000) := 'MYTABLE';
  l_hold_html varchar2(32000) := '';
  l_hold_session_state varchar2(32000) := '';
  CURSOR get_columns IS
  select
    'My Checkbox' column_heading, 'a' column_name
  from dual ;
BEGIN
  l_hold_html := '<TABLE border="2"><THEAD><TR><TH>'
                          || l_hold_table_name
                          || '</TH></TR></THEAD>';
  FOR x in get_columns LOOP
    l_hold_html := l_hold_html ||
                            '<TR><TD>' ||
                            APEX_ITEM.CHECKBOX(20,x.column_name,null) ||
                            x.column_heading ||
                            '</TD></TR>';
  END LOOP;
  l_hold_html := l_hold_html || '</TABLE>';
  htp.p( l_hold_html );
END;And Dynamic Action with properties as described above (only that in my case name of the checkbox is f20)
