IgrGrid bodyTemplate is not displaying values from other cells correctly after scrolling

[agoldenbaum]

Steps to Reproduce:

1. Run the attached sample project.
2. Scroll the grid vertically.
3. Note the "category" column, which has a body template that should take the "id" from the same row.

Result:

There are many cells in the category column that have the incorrect value for the "id" part of the body template, even though it is using the ctx.cell.row.data.id property
