javascript - FB.ui share set the title, message and image

Question

I'm using FB.ui to share a page to Facebook and I'm trying to set the title and message (image if possible but not important). I have this in my site header

<meta property="og:title" content="Your title here" />
<meta property="og:description" content="your description here" />

And my javascript code is

FB.ui({
      method: 'share',
      href: document.URL,
    }, function(response){

        //TODO Proper response handling
        log(response); 
        if (typeof response != 'undefined') {
            alert('Thanks for sharing');
        }
    }); 

From what I've read I just need to og:titleand og:description to set the title and message, but that doesn't seem to work.

Current the title is either coming from part of the part title, or an alt tag on an image, and the message is being populated from just a random paragraph tag.

Facebook documentation says that "share" method has only href parameter, but I have found it is not true. You can use very similar parameters to the "feed" method. This is what I have used and works:

    FB.ui(
    {
        method: 'share',
        href: 'your_url',     // The same than link in feed method
        title: 'your_title',  // The same than name in feed method
        picture: 'path_to_your_picture',  
        caption: 'your_caption',  
        description: 'your_description',
     },
     function(response){
        // your code to manage the response
     });
