Adding button using fnRender and getting oObj.aData[0] bugs

Hi,

I'm having a hard time figuring out where is the bug in the code below :

I have a table and i add in the first column a button, as well as in the last two columns. However, it seems that the oObj.aData[1] varies with time, which is totally beyond understanding.

As you can see in the code, the first column i process uses oObj.aData[0] in the fnRender function, and oObj.aData[0] corresponds to the id from the data.

Further, i process another column, but i can't reach the id from the data : oObj.aData[0] corresponds now to the code of the button of the first column i've processed, while oObj.aData[1] corresponds to the field "day" of the data, and not "id"...

Here are the debug links : http://debug.datatables.net/eyefah

Thanks in advance for you help !
