Unobtrusive Ajax stopped working after update jQuery to 1.9.0

Question

I have just updated jQuery & jQuery UI to: jquery-1.9.0.min.js and jquery-ui-1.9.2.min.js

And... all my unobtrusive Ajax calls (Ajax.ActionLink, Ajax.BeginForm) stopped working properly - they open results in a new page instead of updating the existing div.

And I get this javascript error in Firebug when my page loads:

Code hasn't changed of course, just updated the jQuery scripts using Nuget.

Anyone experienced the same problem ??

Update: This issue has been fixed in the latest NuGet package. I've posted another answer to reflect this. https://stackoverflow.com/a/15539422/714309

In jquery.unobtrusive-ajax.js, find and replace these four lines:

1. $("a[data-ajax=true]").live("click", function (evt) {

   $(document).on("click", "a[data-ajax=true]", function (evt) {

2. $("form[data-ajax=true] input[type=image]").live("click", function (evt) {

   $(document).on("click", "form[data-ajax=true] input[type=image]", function (evt) {

3. $("form[data-ajax=true] :submit").live("click", function (evt) {

   $(document).on("click", "form[data-ajax=true] :submit", function (evt) {

4. $("form[data-ajax=true]").live("submit", function (evt) {

   $(document).on("submit", "form[data-ajax=true]", function (evt) {

You can also generate a new jquery.unobtrusive-ajax.min.js using WebGrease. From the Command Prompt, change to your solution folder and enter this command (assuming your project folder is called Web):

packages\WebGrease.1.3.0\tools\WG.exe -m -in:Web\Scripts\jquery.unobtrusive-ajax.js -out:Web\Scripts\jquery.unobtrusive-ajax.min.js
