How do I move a php call to another div and have it still work

I've looked around a bit, and found issues similar to mine, but not quite the same. I have a page template that is laid out in 4 columns in HTML. Inside column 4, I have a php function echoing a gallery of images.

    <div id="homepage-layout">

        <div id="homepage-column-1">
            <div class="homepage-small"><?php echo get_homepage_img_small_1(); ?></div>
            <div class="homepage-small"><?php echo get_homepage_img_small_2(); ?></div>
            <div class="homepage-small"><?php echo get_homepage_img_small_3(); ?></div>
        </div><!-- End Column 1 -->

        <div id="homepage-column-2">
            <div class="homepage-large-left"><?php putRevSlider("homepage"); ?></div>
        </div><!-- End Column 2 -->

        <div id="homepage-column-3">
            <div class="homepage-med"><?php echo get_homepage_img_med_1(); ?></div>
            <div class="homepage-med"><?php echo get_homepage_img_med_2(); ?></div>
        </div>

        <div id="homepage-column-4">
            <div class="homepage-large-right"><?php putRevSlider("home_small"); ?></div>
        </div><!-- End Column 4 -->

    </div>

I'm using jQuery to change the layout of the site based on the width of the window.

    var column3 = $("#homepage-column-3").contents();
    var column4 = $("#homepage-column-4").contents();
    var swapped = false;

    $(window).on('resize', function() {   
        if( $(window).width() <= 700 && !swapped){
            $("#homepage-column-3").html(column4);
            $("#homepage-column-4").html(column3);
            swapped = true;
        } else if( $(window).width() > 700) {
            $("#homepage-column-3").html(column3);
            $("#homepage-column-4").html(column4);
            swapped = false;
        }
    });

However, when the window size triggers the jQuery, the RevSlider from Column 4 freezes on the image it was displaying at the time, and the only way to get it running again is to refresh the page.

Any thoughts? Or, if this question has been answered already, please point me in the right direction.

Thanks!
