How to reference the ItemType in the current tab in a Dialog box?

I figured this out five minutes after posting it. For me, the context item reference was parent.newItem. So the basic method I made is as follows. It will clone an ItemType in a new tab with the current ItemType's chosen properties when you close the dialog box. 

var inn = new Innovator();
var newItem = inn.newItem("ItemTypeName","add");

var fetchForm = top.aras.getItemByName("Form", "CloneFormName");
var currItem = parent.thisItem;

// set arguments being passed to dialog
var params = {
title: 'Clone Form',
formId: fetchForm.getAttribute("id"), // put your form's id here
aras: top.aras,
isEditMode: true,
dialogWidth: 400, // set width int
dialogHeight: 300, // set height int
content: 'ShowFormAsADialog.html',
item: currItem
};

var callback = function() {
//Perform logic using dialog result here
newItem.getItemByIndex(0).setProperty("config_id", params.item.getProperty("config_id"));
newItem.getItemByIndex(0).setProperty("created_by_id", params.item.getProperty("created_by_id"));
newItem.getItemByIndex(0).setProperty("created_on", params.item.getProperty("created_on"));
newItem.getItemByIndex(0).setProperty("id", params.item.getProperty("id"));
newItem.getItemByIndex(0).setProperty("permission_id", params.item.getProperty("permission_id"));

return top.aras.uiShowItemEx(newItem.node, "tab view", false, false); // in new tab
};

// open the dialog
var topWnd = top.aras.getMostTopWindowWithAras();
var wnd = topWnd ? topWnd : window;
wnd.ArasModules.MaximazableDialog.show("iframe", params).promise.then(callback);
