.set causes endless loop in save function

[Lee]

I have a grid with a local data source and some editable cells. When a user changes one of the cell's values, it needs to run a few different api calls to get the new values for some of the other cells and then display those. The problem is that when I call .set("fieldName", "value") inside the save command, I get an endless loop. How do I fix this? I have attached a Dojo showing what I mean. If you change the name in the Dojo, the age and DOB should change to something else (I know my example is a little silly given the fields but this is just an example, my real fields are different). Instead, I get an endless loop in the console.
