gnome-contacts not showing call nor sms button

[cafe]

I am encountering a issue with gnome-contacts.
Whenever I open a contact, there is no button showing next to the phone numbers, for calls or sms.

Next to the email addresses, I can see the button for sending an email (which works OK and open geary), but no buttons are showing next the the phone numbers.

I checked in /usr/share/applications/gnome-mimeapps.list, which did not have any

Code:

x-scheme-handler/tel
x-scheme-handler/sms

lines, so I added these lines :

Code:

x-scheme-handler/tel=sm.puri.Calls.desktop
x-scheme-handler/sms=sm.puri.Chatty.desktop

but still no luck after that.

Any suggestion ?
