Enum has absolutely no effects

Hi I try to use the enum plugin but it has no effect (sorting is automatically)

http://live.datatables.net/fagezevi/3/watch?html,js,console,output

When I put for example sortable:false for :
"columnDefs": [
{ type: 'enum', "sortable": false, targets: 1 }
],
It's not sortable. So the problem comes from enum.

Any help appreciated!
