Followed by the HTML DOM:
<div class="opt">
    Options
    <div class="panel">
        <h3>i am in panel!!</h3>
    </div>
</div>
When i click on the .opt it would show the .panel content, but then i need to trigger another event to hide the .panel when clicking outside of the .opt element. 
jQuery:
$('.opt').click(function(){
    var $this = $(this);
    $this.find('.panel').fadeIn();
    $this.blur(function(){
        $this.find('.panel').fadeOut();
        alert('i am from blur');
    });
});
Here is a demo JsFiddle
But the blur() method is not executing, what i am doing wrong here technically?
