onPress called on load
<p>I have added a function to the <code>onPress</code> method but the function is automatically triggered on loading the app. Am I doing something wrong?</p>

<pre><code>&lt;TouchableHighlight onPress={this.showMenu()}&gt;
   &lt;View&gt;&lt;/View&gt;
&lt;/TouchableHighlight&gt;

showMenu(){
   this.state.showMenu = true;
}
</code></pre>
