Dynamically Create Select Input Field

I am having an issue while trying to create a Materialize select input field dynamically using jQuery. My goal is to append a div with a select field when a button is clicked. Here is my current code:

$(document).ready(function(){
  $('select').formSelect();
});

$("#addSelect").click(function(){
   $("#addSelect").addClass("disabled");
   $("#addSelect").hide();    
   $("#newContent").append("<div class='row'><div class='input-field col s12'><select> <option value='' disabled selected>Choose your option</option><option value='1'>Option 1</option><option value='2'>Option 2</option><option value='3'>Option 3</option> </select><label>Materialize Select</label><label>Materialize Select</label></div></div><button class='waves-effect waves-light bg-blue btn right' type='button'>Go</button>");  
});

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0-beta/css/materialize.min.css">
<div class="container">
<div id='newContent'></div>
<br>
<button class="waves-effect waves-light bg-blue btn right" id="addSelect">Add Select</button>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0-beta/js/materialize.min.js"></script> 

It adds all the html for the select when I inspect the element, however the select doesn't work. Maybe it's a css issue?

Thanks for any help!
