LikeBTN + CMS dynamic items

Hey Guys,

I am using LikeBtn on my site and I need it to tie into the CMS and count individually for each dynamic item.

The problem is that when I like one and not the other and then refresh the page, both counters were triggered. Here is the script from the website. How do I connect each individual post from the CMS?

<span class="likebtn-wrapper" data-theme="custom" data-f_size="10" data-icon_l="hrt1" data-icon_d="hrt1" data-icon_size="16" data-icon_l_c="#d6d6d6" data-icon_l_c_v="#ff5a5f" data-counter_l_c="#b0b0b0" data-bg_c="rgba(250,250,250,0)" data-brdr_c="rgba(198,198,198,0)" data-label_fs="r" data-identifier="item_1" data-show_like_label="false" data-dislike_enabled="false" data-popup_disabled="true" data-share_enabled="false" data-lazy_load="true" data-tooltip_enabled="false"></span>

(function(d, e, s) {
  if (d.getElementById("likebtn_wjs")) return;
  a = d.createElement(e);
  m = d.getElementsByTagName(e)[0];
  a.async = 1; = "likebtn_wjs";
  a.src = s;
  m.parentNode.insertBefore(a, m)
})(document, "script", "//");
<!-- END -->
