zoomEnabled/exportEnabled error

[CedsTrash]

I'm using your fork at https://github.com/vasilrimar/canvasjs

As soon as I enable zooming (zoomEnabled: true), I get this error message and the chart isn't initialized:

index.js?3e2d:1 Uncaught ReferenceError: setButtonState is not defined at s._updateOptions (index.js?3e2d:1) at s._initialize (index.js?3e2d:1) at s.render (index.js?3e2d:1) at n.render (index.js?3e2d:1)

Did you get this error before ?

Thanks.
