And

Answer 1

Executing this line of code after an AJAX call works for me:

addthis.layers.refresh();

Below is my setup for AddThis

Script

I put this code where I want AddThis to show

How I do AJAX call

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState === 4 && this.status === 200) {

        // Update the DOM

        if (typeof(addthis) != 'undefined' && addthis != null) 
            addthis.layers.refresh();
    }
};
xhttp.open("POST", "", true);
xhttp.send();

Result
