Error Button enable

 I need it to be available only to men when opening a contact. At initialization, there are no rights to the scope. What should be done?

define("ContactPageV2", [], function() {
	return {
		entitySchemaName: "Contact",
		attributes: {
            /* The attribute for storing the availability status of the button. */
            "ButtonEnabled": {
                "dataValueType": Terrasoft.DataValueType.BOOLEAN,
                "type": Terrasoft.ViewModelColumnType.VIRTUAL_COLUMN,
                "value": true
        	}
		},
		messages: {
			"NewPageInfo": {
				mode: Terrasoft.MessageMode.PTP,
				direction: Terrasoft.MessageDirectionType.SUBSCRIBE
			}
		},
		methods: {
			onEntityInitialized: function() {
				this.callParent(arguments);
				this.setButtonEnabled();
				this.sandbox.subscribe("NewPageInfo", function() {
					return this;
				}, this, ["SectionModuleV2_ContactSectionV2"]);
			},
			onPageClick: function() {
				this.showInformationDialog("dwdwdwdwdwdwdw");
			},
			setButtonEnabled: function() {
                if (this.get("Gender").value == "eeac42ee-65b6-df11-831a-001d60e938c6") {
					return("ButtonEnabled", true);        
                }
                else {
					return("ButtonEnabled", false);
                }
            }
		},
