Fire conversion pixel on form success page

We also want to capture the email of the person after the form was submitted. We gave the email form field the ID “EMAIL” and this code is placed in the “thank you page”. But it doesn’t work, we receive submissions from this pixel with “EMAIL” instead of real email that the user put. Any idea how we can fix it?

The pixel code is below.
