Datatable inline button doesn't react on click

Can you please comment why button click handler doesn’t work here:

skis don’t run

Valid syntax is the next

        onClick:{
            play_btn:function(id, ev){
                alert("Start/Stop");
                return false;
            }
        },

So it is an invalid syntax here: http://docs.webix.com/datatable__templates.html

Yes, sorry for the inconvenience.
We have fixed the incorrect description.
