How to include some JS code into a Bootstrap modal using ejs?

Question

I have an ejs page that uses some data including a loop through <%= items[i].id %> and buttons adding or deleting items. Once I transfer delete functionality into a bootstrap modal (creating a delete confirmation dialogue) the loop stops working and only the first array item gets deleted. I'm using Bootstrap 4.0 and their built-in JQuery. Deleting works correctly if performed outside the modal. Thank you for any hints!

<% for (let i=0; i<items.length; i++) { %>
<div class="card w-100 p-3">
  <form method="post" >
    <div class="btn-toolbar" role="toolbar" aria-label="Toolbar with button groups">
      <div class="card-header">
        <%= items[i].name  %>
      </div>
      <div class="card-body">
        <p class="card-text"> <%= items[i].desc  %> </p>
      </div>
      <button formaction="/project" type="submit" class="btn btn-outline-dark" name="editButton" value="<%= items[i].id  %>">Edit</button>
      <button type="button" class="btn btn-outline-danger" data-toggle="modal" data-target="#deleteModal">Delete</button>

    </div>
  </form>
</div>


<!-- Delete Modal -->
 <div class="modal fade" id="deleteModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-body">
        <form class="form-control" action="/delete" method="post">
          <p>Are you sure you want to delete <%= items[i].name  %> ? </p>

        <button type="submit" class="btn btn-outline-danger" name="deleteButton" value="<%= items[i].id  %>">Delete</button>
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
        </form>

      </div>
    </div>
  </div>
</div> 

<% } %>

All <div class="model... have the same id attribute. Wwhen you click on delete button just the first modal is opened. Add <%= i %> as suffix on id :

<% for (let i=0; i<items.length; i++) { %>
    <div class="card w-100 p-3">
        <form method="post">
            ...
            <button data-target="#deleteModal<%= i %>" type="button" class="btn btn-outline-danger" data-toggle="modal" >Delete</button>
        </form>
    </div>

    <!-- Delete Modal -->
    <div id="deleteModal<%= i %>" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
        ...
    </div> 
<% } %>
