How to Set Report Region Title Dynamically

Question

I have code working to periodically refresh a Interactive Report on a page. I have the following code in the page header:
<script type="text/javascript">
//automatic reload IRR
function fnc_reloadIRR () {
gReport.search('SEARCH');
window.setTimeout(fnc_reloadIRR, 10000);
// this means the code execution starts after 10 seconds
window.setTimeout(fnc_reloadIRR, 10000);
</script>
This is working great. The title of the report region is "Intraday Color Code Test - &P1_LAST_REFRESH_TIME."
I have a hidden page item named P1_LAST_REFRESH_TIME on the page that contains the last time the report was refreshed. I am struggling with resetting this value when the report region is refreshed. ( May not even need this item!)
To address this, I created an On Demand application process that gets the Last Refreshed string. I then altered the above code like this:
<script type="text/javascript">
//automatic reload IRR
function fnc_reloadIRR () {
var ajaxRequest = new htmldb_Get( null, &APP_ID., 'APPLICATION_PROCESS=SET_LAST_REFRESH_TIME',0);
gReport.search('SEARCH');
window.setTimeout(fnc_reloadIRR, 10000);
ajaxResult = ajaxRequest.get();
// this means the code execution starts after 10 seconds
window.setTimeout(fnc_reloadIRR, 10000);
</script>
Note the addition of the ajaxRequest stuff. This, too, is working. That is, if I check the value in ajaxResult, it does contain the correct, current time. So far so good.
What I can't figure out is how, now, to get a reference to the title attribute of the Interactive Report Region so that I can reset it.
I AM SOOOOO CLOSE. Can anyone fill in this last part of the puzzle for me?

To clarify, I really just need to know how to get a reference to the Report Region's title so that I can set it to the value currently stored in "ajaxResult"
