Removing will not work, as you are attaching the event to all current elements that exist with the class .remo . When you click Add a new element is created that does not have the handler bound, so it will not remove anything. The solution for this is event delegation, replace this:
$(".remo").click(function(){
$(this).parent('.remo').remove();
});
With this:
$("#a").on('click', '.remo', function(){
$(this).closest('div').remove();
});

$(document).ready(function(){ $('#add').click(function(){ $('#a').append('<div><input type="text" name="arr[]"><button class="remo">remove</button></div>'); }); $('#a').on('click', '.remo', function(){ $(this).parent().remove(); }); });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <body class="ancestors"> <button id="add">Add</button> <div id='a'> <input type="text" > </div>
