Can't Open a Session (Metasploit - Kali)

Hello

I'm trying to do a backdoor with the windows/fileformat/adobepdfembeddedexe exploit. I made the file and all, but when I open that pdf file on my other computer (to test it before to try in my victim's computer), it doesn't start a session on my metasploit. I tried sessions -l to check, and nothing

Any help?
