ajaxhtmlContent and checkboxes

[vijaya bacina]

hi all
i am using ajax htmlcontent tag to dynamically display a table body with list of checkboxes. and a select all checkbox. but now the select all is not working.
here is the code for select all. iused prototype js .

      function handleSelectAllCheckbox() {
        var isChecked = $('select_all').checked;
        var checkboxes = $$('input[name="selectedSection"]');
        checkboxes.each(function(checkbox){
            checkbox.checked = isChecked;
        });
    }

When i use document.getElementsByName("select_all"), i see the value as undefined in firebug console. i think since the select_all checkbox is dynamically appearing on the page may be firefox is not recognizing it.
i changed it to document.getElementById() and it is working in bot IE and firefox. thought it might be usefull to someone

    function handleSelectAllCheckbox() {
        var isChecked = document.getElementById("select_all").checked;
        var checkboxes = document.getElementsByName("selectedSection");
        for(i=0;i<checkboxes.length;i++){
            checkboxes[i].checked = isChecked;
        }
    }

My guess is the element does not have a name on it? Look at the source code of the page with firebug and see if that is the case.
