Change bold black caption in Facebook's sharing dialog - facebook

Question

Is there a parameter to change the bold black text (text "Google" in the example below) in Facebook's sharing dialog? If yes, which one?
My code:
window.fbAsyncInit = function() {
var locationArray = window.location.href.split("/");
FB.init({
channelUrl: locationArray[0] + '//' + locationArray[2] + '/channel.php', //custom channel
xfbml : true,
version : 'v2.6'
});
}
function test(){
alert("test");
FB.ui(
{
method: 'share',
name: 'Sharing Test Name',
caption: 'Sharing Test Caption',
//picture: 'http://4.bp.blogspot.com/-8BR3- K0b_lI/VlZ6b3WCM5I/AAAAAAAARmA/ATbes06U8oU/s1600/mustache-smiley.jpg',
description: "Post to test the sharing funtion available via Facebook's js sdk",
href: 'https://google.de',
},
// callback
function(response) {
if (response && !response.error_message) {
alert('Posting completed.');
} else {
alert('Error while posting.');
}
}
);
}
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/de_DE/sdk.js#xfbml=1&appId={{ fbAppId }}&version=v2.5";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div onclick="test()">share</div>
Research didn't return anything for me (Facebook's docs, here, Google). Is Facebook not allowing to change that part of the dialog text?

There used to be parameters to control this, I may be mistaken however currently I think the only way to do this is using the Open Graph meta tags.
