Your work is exilent but I have an issue in my use of it. I started of by copying the full example using the demo .json file as input to my grid (as done in the example).
Now using the "demo.json" file as source to load data into the grid, I expect the thas file to be updated with my changes in the grid (change of data, use of delete or duplicate button).
How do I get the .json file updated with my changes in the grid?
