Input fields not registering focus event
<p>I am confused as to why this is not doing anything (no errors):</p>

<pre><code>&lt;div id="vehicle_form"&gt;
&lt;input class="dField" type="email" name="email" value="Email"&gt;&lt;br/&gt;
&lt;input class="dField" type="text" name="firstname" value="First Name"&gt;&lt;br/&gt;
&lt;input class="dField" type="text" name="lastname" value="Last Name"&gt;&lt;br/&gt;
&lt;button type="submit"&gt;Submit&lt;/button&gt;
&lt;/div&gt;


$('.dField').focusin(function(){
    console.log('focus');
});
</code></pre>
