Input Text Value Change Validation

Content

I have following scenario

1. Input Text(ID: UserID), defined Value Change Action Chain, validating value against ADP in JS function

2. If JS function returns false, I am calling Error Notification and  "Call Component" - UserID and focus and refresh methods to set control again to UserID

3. If user enter Invalid userID - says ABC, tabout - value change firing, if tabs out 2nd time - value change NOT firing

4. how can I have reset it to fire event again on the same value 

Note: I reset the value of inputtext in action chain, But I believe thats not a good approach....it is firing error notification twice...
