how to meteor react subscribe data bind in component? - reactjs

Question

I am setting up a new meteor react app which subscribes new data from the server. I want to only bind data to main page component. I have following code main page componen.
import React from 'react';
import ReactDOM from 'react-dom';
import RealTime from '../../../lib/client/RealTime';
// TrackerReact is imported (default) with Meteor 1.3 new module system
import TrackerReact from 'meteor/ultimatejs:tracker-react';
import Game from '../pages/components/game';
// > React.Component is simply wrapped with TrackerReact
class MainPage extends TrackerReact(React.Component) {
// Note: In ES6, constructor() === componentWillMount() in React ES5
constructor() {
super();
this.state = {
subscription: {
tasks: Meteor.subscribe('userData')
},
data:{}
}
}
getingData(){
let data=RealTime.find().fetch();
return data;
}
render() {
const gamedata=this.getingData();
console.log(this.getingData());
return (
<div className="container ">
<div className="board-player-top">
<img className="user-pic" src="../../../../../images/player-img-top.png" alt="" title=""/>
<div className="board-player-userTagline">
<div className="user-tagline-component">
Black Name
<i>2202<img src="../../../../../images/user-flag.png" alt=""/></i>
</div>
<div className="captured-pieces">
<img src="images/small-picW-1.png" /> <img src="images/small-picW-2.png" />
</div>
<div className="clock-top">
10:00
</div>
</div>
</div>
<Game/>
<div className="board-player-bottom">
<img className="user-pic" src="../../../images/player-img-bottom.png" alt="" title=""/>
<div className="board-player-userTagline">
<div className="user-tagline-component">
Staick <i>1576<img src="../../../images/user-flag.png" alt=""/></i>
</div>
<div className="captured-pieces">
<img src="images/small-picB-1.png" /> <img src="images/small-picB-2.png" />
</div>
<div className="clock-bottom active">

You can pass data to child component using props but here you can find problem each time you have received the gamedata pass as props to child component then child component will update.
You should simantanilious pass data to each child component.
