how to create popup on cell change event?

Hey @priyatama, could you please provide more details, as it is not quite clear what the intended use case is here? Are you trying to create a general popup in the onCellChange event? Or are you trying to add a popup to each individual cell? Please take a look at this snippet and tell me if any of these is the expected result - https://snippet.webix.com/dm7o5f26.
