I'm sorry, but I wasn't able to verify your Contributor License Agreement (CLA) signature. CLA signature is required for any code contributions to AngularJS.

Please sign our CLA and ensure that the CLA signature email address and the email address in this PR's commits match.

If you signed the CLA as a corporation, please let us know the company's name.

Thanks a bunch!

PS: If you signed the CLA in the past then most likely the email addresses don't match. Please sign the CLA again or update the email address in the commit of this PR.
PS2: If you are a Googler, please sign the CLA as well to simplify the CLA verification process.

please sign CLA. otherwise lgtm

CLA should be signed now, and not sure why the build is failing :(

[IgorMinar]

thanks!

the build failure looks like a saucelabs flake :-/

I was able to make a cla match based on your github username, but I suggest that you sign again with the email address you use to create git commits otherwise you'll be nagged about CLA in the future by our bot.
