Masonry for entries custom information in hover caption

Hi,
In addition to title being shown in the hover caption in masonry for entries, I’d like to display a little custom text like “click here” and a link to, let’s say, “mylink.com”.

I’ve added this code to masonry_entries.php line 794 (using the “text_after”) as follows:

$this->loop[$key]['text_after'] .= "<a href='http://mylink.com'>click here</a>";

But the page appears all messed up, it’s like it disrupted the way javascript builds up the masonry.

However, when I add text without links, it displays perfectly (except for the fact I’d need the link).

$this->loop[$key]['text_after'] .= "click here";

Is there anything I could do to make it work with a link or am I hopeless?

Thank you very much in advance.
