Create a different custom application from the from-internal-custom

I have a application configured on the from-internal-custom in the /etc/asterisk/extensions_custom.conf, i tried to add more than one app like this:

exten => 1235,1,Answer
(… etc)

exten => 1236,1,Answer
(… etc)

When i call 1235 the from-internal-custom app start up ok, but when i try app2 dialing 1236 nothing happens =[

So i want to know how to make the app2 to get working.

App2 is not included in any context. What are you trying to achieve.
