Hey @c0bra .

I commented this line s it was breaking move column functionality. Mouse click event for header cell was not reaching the move column handler. This line was added by you few days back.

I think after some additional pushes my comment was removed because the line(s) changed. Sorry for any mistake/confusion/breakage on my part!

I'm restarting the Travis job and it should run here shortly.

Hi @c0bra ,

That was a different PR where you has made a comment and I also replied @PaulL1 has merged that. In this PR I was mentioning your change in file ui-grid-header-cell.js, which I have commented as it was breaking move column functionality.

[jpuri]

Just did some changes in PR to fix test cases that were breaking.

Thanks again @jpuri for all your work.
