Missing bracket in data events

I've found a bug:
I have a radio button with two values. I want to show/hide some field contained in a segment when user clicks the first or the second button.
It does not work because of a JSON error. The problem is that there is a missing bracket in the code as you can see in the image attached.
The code is:

"identifier":["#pippo"]]'

it should be:
​

"identifier":["#pippo"]}]'

​
Can you please help?
Thanks
Walter
