title: LinkedIn shared link image is not updating with custom url
body: <p>while I am clicking  the contents are being shared. but the image is not being updated. I am working in a single page website application.</p>
  
  <pre><code>var customshareurlLnkd = 'https://www.linkedin.com/shareArticle?mini=true&amp;url=' + encodeURI(globalConfig.main_site_root + '&amp;title=' + data.content.title +'&amp;source=CMS') ;
  
  detailhtml += '&amp;nbsp&lt;a class="sharebtn" href="' + customshareurlLnkd + '" target="_blank"&gt;LinkedIn Share&lt;/a&gt;';
  </code></pre>
