I have a little issue when I use the ColumnChooser plugin. When I use the pop-up for the first time, all the columns are on left part. When I click on a row, everything is OK, the _registerRemoveEvents onClick event is called and my row is moved to the right part. 

But when I click again on the same row, _registerRemoveEvents  and _registerAddEvents onClick events are called, and my row is still on right. I think just the _registerAddEvents has to be called ?

I try to add un unbind to the _applyItemState method, and everything is OK with this change. 

Is it due to a version of one of the library (jQuery, jquery UI, ...)?

I use jqGrid 4.0.0, jQuery 1.5, jQuery UI 1.8.

Any idea ?

Thanks a lot.
