jquery.mobile 1.4.5 Uncaught TypeError: Cannot read property 'concat' of undefined

Look this Documentation

jQuery mobile is locked to some versions of jQuery! You will find a text of

jQuery Mobile 1.3.0 supports versions of jQuery core 1.7.2 – 1.9.1 and we’re actively testing the upcoming 2.0 version too. We will be keeping in sync with their releases to let you take full advantage of the new goodness.

UPDATE

jQuery mobile now works with 2.x versions too, though version 3 still returns the mentioned error.

Use latest version 1.5 ( It is available at: code.jquery.com):
