Jquery change order of divs

Hello experts.
I need some help to finish my code.
I want to change the order of my divs with my goup and godown functions.
Not the ajax function.
I did test this tutorial http://biostall.com/swap-and-re-order-divs-smoothly-using-jquery-swapsie-plugin but it is not what i was looking for because it is not really changing the order but adding a style to display the divs in different positions.
Maybe the insertAfter() can help but i'm not familiar with this.

Any help?
