Call a static function into the class React ES6
<p>I have the following ReactJS class:</p>

<pre><code>import React from 'react'

export class Content extends React.Component {

  static getValue(key) {
    return key
  }

  render() {
    let value = this.getValue(this.props.valueKey);
    return &lt;span dangerouslySetInnerHTML={{__html: value}} /&gt;
  }
}
</code></pre>

<p>But I have the following error:</p>

<pre><code>TypeError: this.getValue is not a function
</code></pre>

<p>I don't understand.  Is this the good way to call a static function? I think react is doing something with statics, but I don't know what.</p>
