API #fnSortNeutral - Get Trigger if sorting?

hi, how may i do this:

the user clicks onto a row and starts the sorting. i want to display a <span id="sorted">Remove Order</span> button AFTER he sorted the table away from standard sorting. i managed to hide the span #sorted after http://datatables.net/plug-ins/api#fnSortNeutral was called. the function works fine and returns to original sorting ... but how do i trigger the initial klick by the user on any row of the table to SHOW the hidden span #sorted again? so the "remove order" span only appears when something is sorted by the user???

hopefully u understand ... :)

thanks for any help ... stefan
