Spark Label component does not seem to fire any kind of "change" or "valueCommit" event

Steps to reproduce:
1. Create a Spark Label and add a listener for a "valueCommit" event or a "change" event.
2. Add some text to the Label's text property.
3.

Actual Results: No events are fired indicating that the text of the Label has changed.

Expected Results: There should be an event to indicate when the Label has changed, just like every other component that uses text.

Workaround (if any):
