bind绑定的回调移除事件监听方法

removeListener移除bind绑定的回调的正确方法：

const EventEmitter = require("events").EventEmitter;
const e = new EventEmitter();
this.data = "134342311";
this.onTest = function () {
    console.log("test=====>" + this.data);
};
e.on("test", this.onTest = this.onTest.bind(this)) // 重点
e.removeListener("test", this.onTest);
e.emit("test");

下面的方法均不能移除监听：

const EventEmitter = require("events").EventEmitter;
const e = new EventEmitter();
this.data = "134342311";
this.onTest = function () {
    console.log("test=====>" + this.data);
};
e.on("test", this.onTest.bind(this)) // 重点
e.removeListener("test", this.onTest);
e.removeListener("test", this.onTest.bind(this));
e.emit("test");
