Getting the Current Row that is being edited in the Update Function

[Steve]

I have a hierarchy grid, what I need to do is when the update function is triggered in the sub grid get the row that is being edited and then based on that row get the corresponding master row.  I added a gist to my sub gird below.

If you look at the gist I need to be able to replace the masterRow variable within the update function, each time a row is edited for the correct values to go to the correct masterRow.

Hi Steve,

The code you have pasted looks correct. The masterRow should be the right one since it is captured in a closure. What is the problem when you run this code? What is the value of the masterRow variable inside the update function of the data source?
