序列化AJax中的数据

Question

I having trouble for adding a multiple Sub Author in my form, I have a form that you can add a sub author. The code works if I only submit one sub author but if multiple sub author the codes not working. Here's the code of my text box in FormAddBook.

<input type="text" class="form-control" placeholder="Sub Authors" name="SubAuthors[]"  maxlength="50" />

And when you want to add another sub author, text box will appear when yun click the Add Sub Author with the same name of textbox.

The codes work when one sub author only but if multiple sub authors the codes not working. Here's the code of my jquery.

$.ajax({ 
      type: 'POST', 
      url: 'proc/exec/exec-insert-book.php',
      data: $('#FormAddBook').serialize(), 
});

Does the Serialize cannot recognize the another text box?
Sorry for my bad english.
