Ajax text with bad code

Describe the problem.
Hey,

I'm trying to retrieve the contact information "last name + first name / position / mail / phone".
I manage to get the mail and the phone but not the name and surname which gives me a "null" (as soon as I am no longer in contact I guess).

This has to do with element click on "contact", I have watched several tutorials on ajax but I didn't succeed.

But how can I manage to get the phone and not the first and last name, I don't understand.

Thanks for your help
