I am trying to create a widget for my custom module. I can't seem to get the js to see the qweb template. Here are the files

services/static/src/js/signature.js

odoo.debug = true;
odoo.define('services.signature', function (require) {
"use strict";
var core = require('web.core');
  var Widget = require('web.Widget');
  console.log("working");
  var Signature = Widget.extend({
   template: "sigPad",
   events: {
      // events binding example
      'click .get-signature': function(){
   console.log("Handle click has been clicked");
   }
    },
   init: function(parent){
   this._super(parent);
   console.log("The signaure has been initiated");
   },
   start: function(){
   var sup = this._super();
   console.log("The start function has launched");
   }
  }); 
  core.form_widget_registry.add('signaturePad', Signature);
});

services/static/src/xml/signature.xml
<?xml version="1.0" encoding="UTF-8" ?>
<templates id="template" xml:space="preserve">
<t t-name="sigPad">
 <div class="panel panel-default mt16 mb0 " id="drawsign">
  <p>This is the signature area</p>
 </div>
</t>
</templates>

views/resources.xml
<?xml version="1.0" encoding="utf-8"?>
<odoo>
  <template id="sws_services_signature_backend" name="sws_services_signature assets" inherit_id="web.assets_backend">
      <xpath expr="." position="inside">
        <script type="text/javascript" src="/services/static/src/js/socket.io-client.js"></script>
        <script type="text/javascript" src="/services/static/src/js/signature.js"></script>
      </xpath>
  </template>
</odoo>

calling it like this inside a form xml

views/views.xml
.....
<field name="signature" widget="signaturePad"/>
......

__manifest__.py
..............
    'depends': ['base','web'],
    # always loaded
    'data': [
        'views/views.xml',
        'views/service_workflow.xml',
        'views/resources.xml',
    ],
    'js': [
      'static/src/js/signature.js'],
    'qweb': [
      'static/src/xml/signature.xml', ]
...........

No matter what I do I get this error:

TypeError: w.set_input_id is not a function. (In 'w.set_input_id($label.attr("for"))', 'w.set_input_id' is undefined)

or If I remove core.form_widget_registry.add('signaturePad', Signature);

and just instantiate it with new and use appendtTo() it tells me it can't find the qweb template. Even though I can inspect the browser and verify that the template is there.

Any idea on how to get this working?
