Unable to get jquery ajax working

[quote author="ssachan" date="1272068156"]thanks a lot !!! problem solved. But can you explain me the reason why not returning a false causes NULL values to appear ?[/quote]

Well it depends on what the element is that's being clicked, but basically it just tells jQuery interupt whatever natural function an element would have performed. So if .button is an anchor, it will keep it from moving forward to a new page.
