Javascript in document library Upload.aspx file not getting called... why??

Hello,

I am using Sharepoint 2010 and have a document library.  The document library comes with an Upload.aspx rather than a NewForm.aspx like lists do.  It appears that I cannot create a custom Upload.aspx page like I can with the Display and Edit forms.  That's fine.  I tried just to add my javascript code in the Upload.aspx file (by editing the file in advanced mode in Sharepoint Designer).  I added my javascript in the same manner that I do in all my List custom forms as well as my EditForm.aspx for my document library, meaning I start with the area:

<asp:Content ContentPlaceHolderId="PlaceHolderTitleAreaClass" runat="server">
    <script type="text/javascript" id="onetidPageTitleAreaFrameScript">

        if (document.getElementById("onetidPageTitleAreaFrame") != null) {
        document.getElementById("onetidPageTitleAreaFrame").className="ms-areaseparator";
       }
   </script>

and I add my javascript inside that script tag with something like:

    function myFunction() {
       alert("I am here");
    }
    _spBodyOnLoadFunctionNames.push("myFunction");

This function never gets called when I click on the "Add document" link to upload a new document to my document library.  I also just tried to add an alert in the script tag but not in a function and that isn't getting called.  Not sure what I am missing because this works in all the other custom and non-custom forms that I use.

Any thoughts? - Peter
