I am trying to create a simple footer that would display on the bottom of each page of the pdf document. I created a class that inherits from PdfPageEventHelper and it is set properly because the OnEndPage() method is called. But my temporary footer is not displaying. Is there something wrong that I am doing in my OnEndPage() method:

public override void OnEndPage(PdfWriter writer, Document document)
    {
        base.OnEndPage(writer, document);

        int pageN = writer.PageNumber;
        String text = "Page " + pageN + " of ";
        float len = bf.GetWidthPoint(text, 8);

        Rectangle pageSize = document.PageSize;

        cb.SetRGBColorFill(100, 100, 100);

        cb.BeginText();
        cb.SetFontAndSize(bf, 8);
        cb.SetTextMatrix(pageSize.GetLeft(40), pageSize.GetBottom(30));
        cb.ShowText(text);
        cb.EndText();

        cb.AddTemplate(template, pageSize.GetLeft(40) + len, pageSize.GetBottom(30));

        cb.BeginText();
        cb.SetFontAndSize(bf, 8);
        cb.ShowTextAligned(PdfContentByte.ALIGN_RIGHT,
            "Printed On " + PrintTime.ToString(),
            pageSize.GetRight(40),
            pageSize.GetBottom(30), 0);
        cb.EndText();
    }
