 * Hello,
 * I created a template to pass a page to my wordpress theme.
    so far ok.
 * Or I block is when I want to call a function when I click on a button on my page.
   
   I don’t know if there is a way for wordpress to do this. My function is in the
   function.php file and when I make a condition if(function_exists (my_function)),
   I put a var_dump with a little message, my function exists.
 * thanks

 * A button on a page exists in the user’s browser. Your functions.php code exists
   on your server. The button cannot directly call your function, the only possible
   communication is over HTTPS/TCP. Hence you need to use Ajax techniques to have
   the browser ask the server to call your function and send the results back to
   the browser.
