Edit true/false depending on the checkbox value in Webix

I've created an editable Webix datatable with the column of checkboxes.

Wondering how can I set edit function to the datatable row depending on the value of the checkbox? Perhaps, I should use

$$("dataTable").attachEvent("onBeforeEditStart", function(. . .){. . .});

But I'm a bit confused what exactly I need to write. And here goes the snippet: http://ift.tt/1QLQWd4
