| 37 | * If the component is initialized, it invokes fireAction to fire the event as well,\r | |
| 38 | * which indicate something has changed. Otherwise, it just executes the action\r | |

| 40 | *\r | |
| 41 | * This is helpful when we only want the event to be fired for subsequent changes.\r | |
| 42 | * Also it's a major performance improvement for instantiation when fired events\r | |
| 43 | * are mostly useless since there's no listeners\r | |
