Depends on your code. You need to post relevant code. But just change the src property on the iframe to the url of the new pdf.

append some random string into the filename to resolve the issue. if your filename is 'filename.pdf' then add some random string into it eg. 'filename_1234.pdf' and each time you generate new pdf append other set of random string into it. You can also try instead to the filename add query string also you need to generate random string for the value of the query string at least your filename is clean if you don't want that method. Good luck.
