onBlur() not working properly

Question

I want the <div> with class .shell-pop to be closed if they click out of the element area. It appears not to fire though, and none of the logs or alerts go off either. I've looked around and everything appears right?

jQuery

$('document').ready(function () {
    updateCart();

    $(".shell").click(function (e) {
        e.preventDefault();
        $(".shell-pop").fadeIn(300, function () { $(this).focus(); });
    });

    $(".shell-pop").on('blur', function () {
        $(this).fadeOut(300);
        window.alert("work");
        console.log("works");
    });
});

HTML

<div class="options-area">
    <div class="options-popup shell-pop">
        <div class="swatches">
            <div class="colors-shell colors" id="green">
                <p class="prices-for-swatch">$14.23</p>
            </div>
            <div class="colors-shell colors" id="pink">
                <p class="prices-for-swatch">$7.23</p>
            </div>
            <div class="colors-shell colors" id="blue">
                <p class="prices-for-swatch">$11.25</p>
            </div>
            <div class="colors-shell colors" id="orange">
                <p class="prices-for-swatch">$10.23</p>
            </div>
            <div class="colors-shell colors" id="default-shell">
                <p class="prices-for-swatch">FREE</p>
            </div>
            <div class="colors-shell colors" id="exit">
                <img src="img/Silhouette-x.png" class="x-logo" alt="exit" />
                <p class="closeit">CLOSE</p>
            </div>
            <div class="shell square">
                <img src="img/controllers.png" class="item-icon" alt="controller-piece">
                <p class="name-of-item">Shell</p>
                <p id="shell_Price1" class="items-price">0.00</p>
            </div>        

Answer 1

Give your <div> a tabindex.

The tabindex global attribute is an integer indicating if the element can take input focus (is focusable), if it should participate to sequential keyboard navigation, and if so, at what position.

Observe the following...

<div tabindex="-1"></div>

$('div').on('blur', function() {
    console.log('blurrr');
});
