have any example about reuse some components with params in a page view

[i2Echo]

import { Test } from "./components/test/test";
import { component } from 'knockout-decorators';

@component("app", `
  <div id="app">
    <test></test>
  </div>   
`)
export class App {
    constructor() {  
       new Test();
    }
}

It's work.

But, if i wanna give some params to test component, how can i do that;
and more 'test' compoent instance with diffrient params in that page?
