filable fields

Options:
I have embeded a PDF with filable fields so the user can type in letters.

I have also a code to insert media look like this:
<iframe frameborder=”1″ height=”200″ name=”frame1″ scrolling=”no” src=”http://……&#8230;./wp-content/uploads/2013/12/what1.pdf” width=”550″></iframe>.

Now to the questions:
How to update or replace thus file on the page directly? is there any option to customize this?
