Change Req- Copy change update - How can i add worknotes "Chnage copied from -"src change number"

[Kachu]

How can we add work notes when change is copied   using Copy change Ui action.Did any one have implemented it or have any community post that can help me modifying this script to add work notes.

Thanks 

Copy Change ui action script :

function OnCopyChangeClick() {

    function addParam(form, name, val) {

        var inp = cel('textarea', form);

        inp.name = name;

        inp.value = val;

    }

    var srcSysId = g_form.getUniqueValue();

    var ga = new GlideAjax('ChangeUtils');

    ga.addParam('sysparm_name', 'getChangeQueryParams');

    ga.addParam('sysparm_src_sysid', srcSysId);

    ga.setWantSessionMessages(true);

    ga.getXMLAnswer(function (queryParam) {

        if (queryParam) {

            var gotoURL = new GlideURL('CopyChangeRelatedLists.do');

            gotoURL.setEncode(false);

            gotoURL.addToken();

            gotoURL.addParam('srcSysID', srcSysId);

            gotoURL.addParam('newSysID', '$sys_id');

            gotoURL.addParam('sysparm_returned_action', '$action');

            var form = cel('form', document.body);

            hide(form);

            form.method = "POST";

            form.action = g_form.getTableName() + ".do";

            if (typeof g_ck != 'undefined' && g_ck != "")

                addParam(form, 'sysparm_ck', g_ck);

            addParam(form, 'sys_id', '-1');

            addParam(form, 'sysparm_query', queryParam);

            addParam(form, 'sysparm_goto_url', gotoURL.getURL());

            form.submit();

        }

    });

}
