Passing collection description from edit.php through auto.js into edit_row.php

Permalink
I'd like to get the collection description of a page added with the page selector to the form of a block—a manual nav or an image slideshow, for example. Following snippets from jordanlev's Manual Nav add-on sensibly demonstrate the passage of the collection name as "tempLinkText." I've had some success with makeshift efforts to get the collection description along with the name into edit_row.php though initially the value returns as undefined.

Any help would be great, thanks up front.

<!-- form.php -->
<div id="ccm-edit-rows">
<?php  foreach($links as $rowInfo) {
    $rowInfo['rowId'] = $rowInfo['position']; //we need some arbitrary unique number other than link cID, because there might be more than one menu item pointing to the same page)
    $rowInfo['pageName'] = Page::getByID($rowInfo['linkToCID'])->getCollectionName();
    $this->inc('edit_row.php', array('rowInfo' => $rowInfo));
} ?>
</div>
<div id="rowTemplateWrap" style="display:none">
<?php 
$tmpRowInfo = array(
    'rowId' => 'tempRowId',
    'linkToCID' => 'tempLinkToCID',
    'linkText' => 'tempLinkText',
    'pageName' => 'tempLinkText',

// auto.js
manualNav_selectSitemapNode = function(cID, cName) {
    ManualNavBlock.addRow(cID, cName);
}
var ManualNavBlock = {
    init:function(){},
    addRowNewId:0,
    addRow: function(cID, cName) {
        this.addRowNewId--; //negative counter - so it doesn't compete with existing rowIds
        var rowId=this.addRowNewId;
        var templateHTML=$('#rowTemplateWrap .ccm-edit-row').html();
        templateHTML=templateHTML.replace(/tempRowId/g,rowId);
        templateHTML=templateHTML.replace(/tempLinkToCID/g,cID);
        templateHTML=templateHTML.replace(/tempLinkText/g,cName);
        var newRow = document.createElement("div");
