Reload (or initialize) addThis social share buttons. Useful when implementing addThis in a SPA (Single Page Application).

addthis_reload.js

// Reload (or initialize) addThis social share buttons.
// IMPORTANT: make sure you put in a correct pubid on line 7.
window.addthis_reload = function () {
  if (!window.addthis) {
    // Load addThis, if it hasn't already been loaded.
    window['addthis_config'] = { 'data_track_addressbar' : false };
    $('body').append('<script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid={YOUR PUBID HERE}"></script>');
  } else {
    // Already loaded? Then re-attach it to the newly rendered set of social icons.
    // And reset share url/title, so they don't carry-over from the previous page.
    window['addthis_share'].url = window.location.href;
    window['addthis_share'].title = window.document.title;
    window.addthis.toolbox('.addthis_toolbox');
  }
}

Changing this:

window['addthis_config'] = { 'data_track_addressbar' : false };
$('body').append('<script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid={YOUR PUBID HERE}"></script>');

to this:

window['addthis_config'] = { 'data_track_addressbar' : false, 'pubid': 'YOUR PUBID HERE };
$('body').append('<script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js"></script>');

Will prevent problems with AddThis detecting the profile ID on the page.

addthis.layers.refresh();

Did the trick for me.

@Jamiek94 Thanks for the solution.
