paypal button for react.js

so I'm trying to get the paypal button to show up on my app but I can't get it work. I'm basing it off this jsfiddle. https://jsfiddle.net/rbacekkb/

I tried to put into my app but the button isn't showing up on the page that I want. I don't know what i did wrong.

paypal.jsx

import React from 'react';



class PayPalButton extends React.Component {
    constructor() {
        super();
        // you can take this value from a config.js module for example.
        this.merchantId = '6XF3MPZBZV6HU';
    }

    componentDidMount() {
        let container = this.props.id;
        let merchantId = this.merchantId;
        window.paypalCheckoutReady = function() {
            paypal.checkout.setup(merchantId, {
                locale: 'en_US',
                environment: 'sandbox',
                container: container,
            });
        }
    }

    render() {
        return(
            <a id={this.props.id} href="/checkout" />
        );
    }
}

module.exports = PayPalButton;

trying to get it show up in this page currently for testing.

home.jsx

import React from "react";
import {Grid,Row,Col,Button,Jumbotron, Carousel, Panel} from "react-bootstrap";
import PayPalButton from "../components/paypal";
import {LinkContainer} from 'react-router-bootstrap';
import {Link} from 'react-router';

const title = (
    <h3>Fashion News</h3>
)

const title2 = (
    <h3>Fashion History</h3>
)

const title3 = (
    <h3>Fashion Items</h3>
)

const Home = React.createClass({
  displayName: "Home page",
  componentDidMount(){
    console.log(this.props)
  },
  render(){
    return (

        <PayPalButton id="button" />

    );
  }

});
module.exports = Home;
