It is always 0 because onpopulate is not called until render time,
where the value of the label is set to a fixed string in your model.
the solution is to wrap totalCredit in a model. also make sure to
reset it 0 again in the onpopulate if the item index =0 or the value
will continue to increase with each rendering.
