Pass props in Link react-router

I am using react with react-router.
I am trying to pass property’s in a “Link” of react-router

var React  = require('react');
var Router = require('react-router');
var CreateIdeaView = require('./components/createIdeaView.jsx');

var Link = Router.Link;
var Route = Router.Route;
var DefaultRoute = Router.DefaultRoute;
var RouteHandler = Router.RouteHandler;
var App = React.createClass({
  render : function(){
    return(
      <div>
        <Link to="ideas" params={{ testvalue: "hello" }}>Create Idea</Link>
        <RouteHandler/>
      </div>
    );
  }
});

var routes = (
  <Route name="app" path="https://stackoverflow.com/" handler={App}>
    <Route name="ideas" handler={CreateIdeaView} />
    <DefaultRoute handler={Home} />
  </Route>
);

Router.run(routes, function(Handler) {

  React.render(<Handler />, document.getElementById('main'))
});

The “Link” renders the page but does not pass the property to the new view.
Below is the view code

var React = require('react');
var Router = require('react-router');

var CreateIdeaView = React.createClass({
  render : function(){
    console.log('props form link',this.props,this)//props not recived
  return(
      <div>
        <h1>Create Post: </h1>
        <input type="text" ref="newIdeaTitle" placeholder="title"></input>
        <input type="text" ref="newIdeaBody" placeholder="body"></input>
      </div>
    );
  }
});

module.exports = CreateIdeaView;

How can I pass data using “Link”?
