@Reto.K after creating element you have to insert it into document with appendChild(): developer.mozilla/pl/docs/Web/API/Element/appendChild – mx0 Commented Aug 26, 2016 at 9:20

Try it :

$(document).ready(function(){

$("button.plus").on("click",function(){

$("div:last").after("<div class=item><p>Title</p></div>");

    })

})

This is Demo : UpdatedDemo

Do it like this

 <div id = "main">
 //your same html code

 </div>

 <script>
function newPerson() {
var newdiv  = document.createElement('div');
newdiv.className+='item';

var newp = document.createElement('p');
newp.innerHTML = "TItle";

newdiv.appendChild(newp);
document.getElementById('main').appendChild(newdiv);
}
 </script>

You need to create the element through JS and append it to the document

This is another way to solve it:

function newPerson() {
  $('#wrapper').append('<div class="item"><p>Title</p></div>')
}

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper">
  <div class="plus">+</div>
  <button onclick="newPerson()" class="plus">
    <div class="item">
      <p>title</p>
    </div>
  </button>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
  <div class="item">
    <p>Title</p>
  </div>
</div>
