ckeditor plugin output in select?

Question

JavaScript

Greetings, there is a plug-in, its task is simple, it displays a list and, when a name is selected, it is inserted into the editor.

So he does his job.
But now it is necessary that it deduced the data from a DB. Ajax is used for this.

Now there is no dropdown list on the select, it's empty. What's wrong? Where is the mistake?
there is this in ajax, it sort of displays the name, but not when choosing from the list (it is empty), but when clicking on the plugin itself in ckeditor
console.log(adminpanelHeroes[key].name);
I hope I explained it clearly)
