Plugin dont Work Inside AJAX Call

All AJAX calls in WordPress run through admin. So if you wrap something inside 

if ( ! is_admin() )
{
    // stuff
}

then the AJAX call would not be able to know about this part. In other words, it does not get executed. I don’t know what this plugin specifically does, but if only one part does not get executed, there’s a high chance that this is the problem.
