caption not in href so not clickable

We are laying the caption over the images but found that the caption are not in the href that holds the slide

I fixed in JS but should be in the plugin

// hack the slider
    $slides = $('.slides li');

    $slides.each( function(){
        $source = $( '.caption-wrap', this );
        $dest = $( 'a:last', this );
        $( $source ).detach().appendTo( $dest );
    });
