Dynamic menu for each Item callback based

[cat0rgi0]

I'm looking for a way to populate a dynamic context menu in a callback ajax call. I mean i found a method to create dynamic numbers of row(li) but it works on modyfing directly the DOM element and i don't think is a good practice especially because i have to add an hanlder function click for every element of menu. So i don't understand reading all requests and issues if the object menu in .on('contextmenu',d3.contextMenu(menu,...must only be instantiated before contextMenu function called.
