Here's how I implemented it working from @mg1075's code. I wanted a bit more generic code so as not to have to assign classes to the modal trigger links/buttons:

Tested in Twitter Bootstrap 3.0.3.

HTML

<a href="#" data-target="#my_modal" data-toggle="modal" data-id="my_id_value">Open Modal</a>

JAVASCRIPT

$(document).ready(function() {

  $('a[data-toggle=modal], button[data-toggle=modal]').click(function () {

    var data_id = '';

    if (typeof $(this).data('id') !== 'undefined') {

      data_id = $(this).data('id');
    }

    $('#my_element_id').val(data_id);
  })
});

I find this approach useful:

Create click event:
```
$( button ).on('click', function(e) {
    let id = e.node.data.id;

    $('#myModal').modal('show', {id: id});
});
```
Create show.bs.modal event:
```
$('#myModal').on('show.bs.modal', function (e) {

     // access parsed information through relatedTarget
     console.log(e.relatedTarget.id);

});
```
Extra:

Make your logic inside show.bs.modal to check whether the properties are parsed, like for instance as this: id: ( e.relatedTarget.hasOwnProperty( 'id' ) ? e.relatedTarget.id : null )

Your code would have worked with correct modal html structure.

$(function(){
  $(".open-AddBookDialog").click(function(){
     $('#bookId').val($(this).data('id'));
    $("#addBookDialog").modal("show");
  });
});

<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>


<a data-id="@book.Id" title="Add this item" class="open-AddBookDialog">Open Modal</a>

<div id="addBookDialog" class="modal fade" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-body">
       <input type="hidden" name="bookId" id="bookId" value=""/>
      </div>
    
    </div><!-- /.modal-content -->
  </div><!-- /.modal-dialog -->
</div><!-- /.modal -->
</html>

Bootstrap 4.3 - use code from below snippet - more here

$('#exampleModal').on('show.bs.modal', function (event) {
  let bookId = $(event.relatedTarget).data('bookid') 
  $(this).find('.modal-body input').val(bookId)
})

a.btn.btn-primary.open-AddBookDialog {color: white }

<!-- Initialize Bootstrap 4 -->

You can try simpleBootstrapDialog. Here you can pass title, message, callback options for cancel and submit etc...

Here is a cleaner way to do it if you are using Bootstrap 3.2.0.

Link HTML

<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>

Modal JavaScript

//triggered when modal is about to be shown
$('#my_modal').on('show.bs.modal', function(e) {

    //get data-id attribute of the clicked element
    var bookId = $(e.relatedTarget).data('book-id');

    //populate the textbox
    $(e.currentTarget).find('input[name="bookId"]').val(bookId);
});
