Multipage PDF made with reportlab not indexing the information displayed

Question

I'm trying to create a multi page PDF using a for loop. Reportlab creats the correct number of pages but dosn't seem to index the text to be displayed. The page number indexes correctly but not the data.

from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import A4


def Multipage(data):
    c = canvas.Canvas("multipage.pdf", pagesize=A4)
    w, h = A4
    page_count = len(data)
    textobject = c.beginText(10, h - 20)
    for page in range(len(data)):
        page_num = c.getPageNumber()
        page_txt = "Page %s of %s" % (page_num, page_count)
        for line in range(len(data[page])):
            textobject.textLine(data[page][line])
            print(data[page][line])
        c.drawText(textobject)
        c.drawString(w - 90, 10, page_txt)
        c.showPage()
    c.save()
    
    
if __name__ == '__main__':
    checks = [["line one pg1", "line two pg1"],["line one pg2", "line two pg2"],["line one pg3", "line two pg3"]]
    Multipage(checks)
