Title: BHV-12661: update delegated fucntion handle routine

## Issue
Improper delegated function is handled in dispatchEvent fuction

## Cause
In many cases, this[nom] can be "" in dispatchEvent function.
Now current rouine finally makes bubbleUp event in this condition

## Fix
Catch a condition that is ' this[nom] == "" ' so that don't makes bubbleUp event.
