Fix duplicate indicator addition by preventing multiple event listeners

Browse Source 
Added eventListenersSet flag to track if event delegation has been setup.
Only call setupEventListeners() once during initial render to prevent
adding multiple event listeners that cause 'addIndicator' to be called
multiple times when clicking a button once.

This fixes the bug where one click adds 8 identical indicators.
