Jquery :: Controlling The Loading Of Divs Asynchronously

I am trying to reload the contents of a div asynchronously using jquery. It works fine if the link/button to do so is outside of the div I am reloading, but I need the button to be inside the div I am reloading and it does not work if I do it from there. I have thought about overlaying divs but I need the buttons to be very exactly positioned as its a graphical representation of a map and recoding the way the buttons are placed would not only annoy me but be very difficult.

You see its an isometric view of a square, and the buttons need to be placed right along the edges of the 'diamond' therefore always coming inside or on top of the div that contains the map view. So, is what I am trying to do impossible or might I just be going about it the wrong way ? If it is the latter then I will post some code.
