$.ajax() does an _assynchronous_ XMLHttpRequest. It returns immediatelly and 
does not wait for the request to finish. After the call has returned the text 
can simply not be there. Try it this way:

function loadModuleHTML(p_id, p_moduleIndex) {
  $.ajax({
    type: "POST",
    url: "get_file_contents.php",
    data: "mod_index=" + p_moduleIndex,
    dataType: "html",
    error: function(req, errorMsg) {
      alert("An error occurred: " + errorMsg);
    }
    success: function(h) {
      alert(h);
      $('#'+p_id).html(h); // yes, that is what jQuery is for
    }
  });
}
