Deactivate input field, NOT set interactable to false

How do I ensure my inputfield in UI 4.6 stops picking up keyboard input after I have submitted using enter or clicked on another object?

Setting intractable to false makes the input field no longer pickup mouse clicks.

This is a clarification of this question:

I have tried the following but this doesn't work:

     myInput.onEndEdit.AddListener(delegate{StopInput(myInput);});
 
 void StopInput(InputField _input) {
         print (_input.text);
         _input.DeactivateInputField ();
     }

Where myInput is a inputfield created in c#.
