Email, phone number and job title are not registered in the new contact genereted by landing page
I am creating a landing page to register participants.
I am using the 'Event participant registration form' and the participant is added correctly to the detail and a new contact is created, but the informations of email, phone and job title of the contact are missing. These informations are required to make the form work.
I first tryed to map the values with 'Contact.Email' , 'Contact.JobTitle' and 'Contact.Mobile' but JQuery does not recognize the '.' and does not perform the post method.
So I tried with 'Contact\\.Email' to avoid a JQuery error, but it gave the same empty result.
So I don't understand what I should do to obtain an update of the Contact object based on the form input of the landing page.
Does anybody know how to solve this problem?
