pdf form containing qr code

In our Coldfusion application there is a PDF form (created in Adobe Professional) that contains a QR code field. The QR code reflects Field X of the form.
When I make changes to X in Adobe Professional, a corresponding QR code is printed into the form. However, if I fill out Field X using ColdFusion (cfpdfformparam), the QR code is not updated.

Is it possible in Coldfusion to have the QR code field change dynamically? Is there any parameter or function achieving that behavior or is there a property of the used form? 
Of course I know I can create the QR code as an image and load it into an image field - this is plan B for me.
