unwrap... doesn't seem to work for me.

I am passing the name of a div when clicked to a function. This function wraps the div around another div and is then meant to unwrap the div... however the unwrap does not work...
I know htis is a pointless exercise, but please humour me. regards J
 
  1. $('.slideDownBtn').click(function(){
    wrapFunction('.testDiv');})
  2. function wrapFunction(divToSlide){
    divToSlide=$(divToSlide);
    divToSlide.wrap('<div class="jwrapper"/>');
    divToSlide.unwrap();
    }
