Label renderer, onCreateLabel never called

[ben.gillis]

I need to create a label on-the-fly as the graph is generated. But, label renderer and onCreateLabel are never called back.

label renderer seems easy enough:

label: {
renderer: function (value) {
... // this is never called!
}

the onCreateLabel is not called either (http://docs.sencha.com/ext-js/4-0/#!/api/Ext.chart.Label).

An example would be most helpful.

That uses the renderer config on the label object.
