Output HTML with Transform Function

Hi

I have a checkbox in my contact-form with 0/1 values
I output the stored data with:

[cfdb-table form="..." trans="checkbox=myFunction"]

In myFunction() I’d like to output HTML depending on the value of checkbox. But the function shows HTML as code and not as HTML.
What can I do?
