MM module loading stale data??

[makerofmirror12]

I have a node helper file that is doing this:

const NodeHelper = require("node_helper");
const fs= require("fs");

module.exports = NodeHelper.create({
//here comes the part of the nodehelper after the 3 dots as posted above

        socketNotificationReceived: function(notification, payload) {
                if(notification === "START"){
                        this.config = payload;
                        this.readData();
                        setInterval(() => {
                                this.readData();
                        }, this.config.updateInterval);
                }
        },


        readData: function (){
        //to read a file to do the following
                fs.readFile('/container.html', 'utf8', (err, data) => {
                if (err) throw err;
                this.sendSocketNotification('DATA', data);
                });
        }
})

This seems to present the same info… despite changing what it is in the file: container.html

Why is that? Isn’t think loading up on every npm start?
