head pain with context menu

Webix JS
#1

I try to figure out how webix can use a own context menu. For this I used a textarea.
{
//Editor
view:“mytext”,
id:“bxfeditor2”,
name:“bxfeditor2”,
height:400
}

for this I define:
webix.protoUI({
name: “mytext”,
on_context:{}
},webix.ui.textarea);

And finally I added the menu to the control.

$$(“cmenu”).attachTo($$(“bxfeditor2”));

But no result. What I do wrong?

solved. Please ignore.
