cannot disable or destroy sortable element

[gxfan]

in my project, i first run some codes like this: $('#element').sortable({activeClass:'active'});

but when i run $('#element').sortable(‘disable') some time later, i have some error messages in the console: Uncaught TypeError: undefined is not a function

it occurs in line 969 of file touch-dnd.js.

Thanks for reporting. This is strange. Could you provide example code?
