LPS-41278 - UI: page name still exists in page navigation bar when the name has already deleted from name field on IE9

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-41278.

NOTE: In IE9 the 'input' event doesn't fire when characters are deleted from input tag, only when they are added. Tested this fix on IE7-10, FF, Chrome, and Safari. 'valuechange' works across the board. - @Robert-Frampton 

Please let me know if you have any questions.  Thanks!
