Thread:Extension talk:Semantic Forms Inputs/Buttons don't do anything/reply (3)

I have the same problem: clicking the Buttons does not trigger any reaction. I am running:
 * MW 1.16.1
 * Semantic MediaWiki (Version 1.6)
 * Semantic Forms (Version 2.2.1)
 * Semantic Forms Inputs (Version 0.4.1)

I did the ctrl-shift-J and saw several errors, but nothing that has to do with Semantic Forms Inputs. At least I did not see it. But Internet Explorer told me the problem:

Message: The object does not support this value oder method Line: 154 Character: 2 Code: 0 URI: http://xxxx/mediawiki/extensions/SemanticFormsInputs/libs/datepicker.js

Line 154 in my datepicker.js is as follows: var disabledDates = jQuery( input ).datepicker( "option", "disabledDates" ); What could be wrong there? Any help is greatly appreciated
