Delegate onKey doe's not work.

[Sahkan]

1. void Awake()
2.         {
3.                 UIEventListener.Get(laterInputField.gameObject).onKey += laterInputField_Typed;
4.         }
5.  
6. void laterInputField_Typed(GameObject go,KeyCode key)
7.         {
8.                 print ("laterInputField_Typed");
9.         }
10.  

This example won't print anything, and i'v checked, the other delegates are working fine .
I'm working from version 3.5.3 and i can't upgrade at the moment, so maybe a piece of missing code or something that can fix it will be very appreciated. Thanks.

EventDelegate.Set(laterInputField.onChange, LaterInputField);
