Doing things other than merely displaying text with JSON loaded data

alpswd

I am able to follow this guide to display my JSON data -- http://www.datatables.net/examples/ajax/objects.html
However, Im stumped as to how to do something other than simply display the data in the table cell.
For example, If I wanted to do something like the following for a all cells in a column:
<td>$<input min="1" max="100000" value="[[JSON VALUE]]" onclick="updateCalculations(this.id)"</input></td>
