column width doesn't get calculated properly

This seems to have been caused by pull request #161

Basically the column width doesn't seem to get calculated properly if the rows are added after the grid has been bound.

I made a plunker here based on the original server-side paging example. http://plnkr.co/edit/rJjPr8nbbiTPejg3LyKx

Thanks very much for looking into this.

Start with the server-side paging example and the Plunker, then inspect the changes from pull request #161 that calculate column widths. Reproduce the issue by adding rows after the grid is bound and trace why the widths remain incorrect. Done means columns are calculated correctly in that sequence and the Plunker no longer reproduces the bug.
