The set Data method is the correct place to do this; since itemRenderers get recycled. Using creationComplete will only fire the first time that the itemRenderer is instantiated. From then on, the same renderer may be re-used in another cell with different data; after actions like scrolling. This makes perfect sense why the displayed data wasn't changed.
