Hi @claudio-d-ambrosio ! There could be several reasons why the JavaScript code inside the onReady() function of dynamic pages is not being executed. One possible reason is that there may be a syntax error or some other error in the code that is causing it to fail. You can check the browser console for any error messages that may be related to the code. As for why placing a button’s onClick event on dynamic pages “forces” the code to run, it’s difficult to say without more information about the code and how it’s being used. It’s possible that the button click is triggering some other code that is needed for the onReady() function to work correctly. Good luck!
