Custom insert with onCreateMenu

I've been struggling with how to use the onCreateMenu function to auto populate valid values that I would like to insert into the json. I realize I would use editor.update(), but I basically want the functionality the same as insert with my custom key/type pair.

This would allow me to restrict valid values to the predefined context menu submenu items.

Here is my current function, and I think this is pretty clear what i'm trying to do. Any tips/tricks that I may be missing?

```
onCreateMenu = (items, node) => {
debugger;
const submenu = this.state.keywords.map((keyword: Keyword) => {
return {
type: "append", // doesn't affect callback
text: keyword.keyword,
title: keyword.title,
className: "not-used-right-now",
click: _.bind(function (a, b, c, d) { // all these values are undefined
debugger
node._onAppend(`keyword.keyword`, {});
}, this),
};
});

items.push({
type: "append",
text: "Cubby Values",
title: "Show the possible valid keywords for this property",
className: "no-used-right-now",
submenu,
});

//debugger;

return items;
};
```
