Add conditional button into the active row of detail

Hi all,

Further to the thread below, is it possible to make a button added to the active row of a detail conditional?
Add button into the active row of detail | Community Creatio

I want to make the button enabled on a certain condition but when I add the enabled and visible values to the Diff of the datagrid, I get no result (tried passing "enabled": false to check it wasn't an issue with the CanSplitFlights method)

define("UsrFlightsDetail", ["ProcessModuleUtilities"], function(ProcessModuleUtilities) {
	return {
		entitySchemaName: "UsrFlights",
		details: /**SCHEMA_DETAILS*/{}/**SCHEMA_DETAILS*/,
		diff: /**SCHEMA_DIFF*/[
			{
				"operation": "merge",
				"name": "DataGrid",
				"parentName": "Detail",
				"propertyName": "items",
				"values": {
					"activeRowActions": [],
					"activeRowAction": {"bindTo": "onActiveRowAction"}
				}
			},
			{
				"operation": "insert",
				"name": "DataGridActiveRowSplitFlights",
				"parentName": "DataGrid",
				"propertyName": "activeRowActions",
				"values": {
					"className": "Terrasoft.Button",
					"style": Terrasoft.controls.ButtonEnums.style.BLUE,
					"caption": "Split flights",
					"tag": "SplitFlights",
					"visible": true,
					"enabled": CanSplitFlights
				}
			}
		]/**SCHEMA_DIFF*/,
		methods: {
            CanSplitFlights: function() {
                var FlightTypeId = this.getActiveRow().get("UsrFlightType");
				var FlightTypeValue =  FlightTypeId  && FlightTypeId.value;
 
				if (FlightTypeValue == '3a0d3b1b-9af5-472a-bac9-e785500ac4e9') {
					return true;
                }
                return false;
            },
			onActiveRowAction: function(SplitFlights) {
				switch (SplitFlights) {
					case "SplitFlights":
						this.onSplitFlights();
						break;
					default:
						break;
				}
			},
			onSplitFlights: function(){
				ProcessModuleUtilities.executeProcess({
					sysProcessName: "UsrSplitFlights",
					parameters: {
						FlightId: this.getActiveRow().get("Id")
					}
				});
			},
