on_change: allows row paramter to be passed in callback

[dam13n]

Let me know about any improvements to make.

[dam13n]

Please hold on this. I messed it up.

I don't have any idea on more improvement... except maybe callback.call if arity == 0 ? So I you want to add it, do it, otherwise, I'll merge like this

[dam13n]

Ok, I added your change. I can't get specs to pass due to an error with: XLFormRowDescriptorTypeImage

I removed the image cell from PM-XLForm because I PR it in XLForm and it was accepted, did you ran rake pod:update ? (btw, the specs are passing on travis)

[dam13n]

Yea, I tried updating the pod and cleaning. Using the latest from XLForm. No idea atm.

Thanks @dam13n

For your error, do you use the master version or the release ?
