Tagbox within JQuery UI Dialog Modal

[psaliente]

Currently, I am implementing tagbox inside a jquery ui dialog. when I was testing the dropdown, type a few letters and then click on an item, the click event (row.el.on('click'...) was not fired. This happens when I test it with IE8 but on other browsers (ff, chrome) tagbox is fine inside the dialog.
