The JavaScript config object would look like this:
{
eventClickHandling: "Select",
onEventSelect: function(args) { OnEventClick(args.e); },
eventDoubleClickHandling: "Enabled" // it's disabled by default
}
EventClickJavaScript is not translated to onEventClick because it would cause OnEventClick(e) to be fired twice.
Double click event is enabled (eventDoubleClickHandling) but your config is missing eventDoubleClick event handler.
