Found the proper way to bind custom functions with ContextMenu: Binding the callback with “fat arrow” provides the context of the holding angular component, so I could fire my own function.
contextMenu: any = {
items: [{
key: “delete”,
name: ‘Remove Table’,
callback: (key, options) => {
console.log(“call my function”,this); this.myOwnFunction();
}
}]
};
