@javismiles - mRender passes in three parameters:

1. The data for that cell
2. The data type requested
3. The data for the whole row

It doesn't just conveniently pass in the three parameters you want ;-). You need to use the third parameter - something like row.param1, row.param2, etc (assuming you call the third parameter row.
