hi – there is probably a very easy workaround to this, but when the grid is loaded dynamically, a callback .onCellUpdate() seems to freeze up the grid.
As you can see, the callback accepts a few arguments.
Generally, this callback is for validating the new cell value.
You may validate the cell; if it is valid, you should invoke the confirm function from the arguments.
The function accepts true if the cell is valid and false if it is not: https://codepen.io/svetoslavb04/pen/RwEaZvM
