I have a custom node using editor javascript. I want to customize the auto-completer in my node.  
I modify as below:

```auto
this.editor = function (id, value, defaultValue) {
...
 mode: "ace/mode/javascript",
}
this.editor.completers.push(customEditor);

```

I run well in my node. But one big problem is that the completer in the node [function] editor was changed. How can the custom completer work in my node scope only?
