Getting value from .data jquery

I need to put some caption in my images with lightbox plugin, it calls the caption with the function below:

setCaption: function () {
    var caption = $(plugin.current).data("caption");
    if(!!caption && caption.length > 0) {
        plugin.caption.fadeIn();
        $('p', plugin.caption).text(caption);
    }else{
         plugin.caption.hide();
    }
 },

I don't know the place in html that i have to type the caption to the function get it, could you help me?

Say the plugin.current element is a <span> then you do something like:

<span data-caption="My caption">Hello, World!</span>

The convention for .data will look for data attributes on an element. The preface data- is the indicator, and the suffix, caption is the name in this case, hence data-caption.
