i'm not expert on openxml think you're missing adding actual reference footnote in body text, tweaked code , footnote in document. hope helps or @ least gets started.

run run = para.appendchild(new run()); run.appendchild(new documentformat.openxml.wordprocessing.text("this main text of document")); var footnoteref = new footnotereference() { id = 1 }; run.append(footnoteref);
