CADPHP execute php.file on click button

HI,
The cadphp is working properly when code "cadphp:p1:test" is added at the beginning of the line. But i have two questions:

• Is it possible to execute it when a button is clicked?
• Is it possible to pass a parameter to the php code?
  if not, how can I do it with grav?

Best Regards,
Ricardo
