I want to change that variable from component because i m using conditional rendering and if showRegister = false => confirm password box will be hide..

let app = new Vue({
  el: '#your-container-id',
  data: {
    randomString: "hello worlt",
  },
  methods: {
  	//...
  }
});

mp.events.add("correct.grammar", function() {
  yourBrowser.execute("app.randomString = 'Hello World!';");
});
