Could you please provide details of the JS error

You have not provided where you have defined the Javascript code related to your question but one thing that I noticed in your error detail is '_dopostback'
the error is:_dopostback('gridview','edit$')

It should be __doPostback. Looks like you are tryng for forced postback from Javascript. If so, use double underscore before the doPostback thing.
