TypeError: this[("text" + "Handler")] is not a function

[Luis Humberto Balam Gonzalez]

Hi boys,
I'm a noob.
I try Polymer

I modified the original example project, like this:

<link rel="import" href="bower_components/polymer/polymer.html">
<link rel="import" href="bower_components/core-ajax/core-ajax.html">

<polymer-element name="post-service" attributes="posts">
  <template>
    <style>
    :host {
      display: none;
    }
    </style>
    <core-ajax id="ajax"
      auto
      url="example.json"
      on-core-response="{{postsLoaded}}"
      handleAs="json">
    </core-ajax>
  </template>
  <script>
  Polymer('post-service', {
    created: function() {
      this.posts = {};
    },
    postsLoaded: function() {
      // Make a copy of the loaded data
      this.posts = this.$.ajax.response;
    }

  });
  </script>
</polymer-element>

My Json Archive:

{"record_0":{"codigo":"1901983","primerapellido":" MIRANDA","segundoapellido":"BARRERA","nombres":"BLANCA ROSA ","curp":"IGNORAR","tipo":"soundlike"},"record_1":{"codigo":"1901042","primerapellido":"AKE","segundoapellido":"PAT","nombres":"NEYBI DEL ROSARIO","curp":"IGNORAR","tipo":"soundlike"},"record_2":{"codigo":"1900805","primerapellido":"AKE","segundoapellido":"RODRIGUEZ","nombres":"ROSALINDA","curp":"AERR810508MYNDS","tipo":"soundlike"},"record_3":{"codigo":"20100096","primerapellido":"ALFONSO","segundoapellido":"CASTILLO","nombres":"ROSA MARIA","curp":"IGNORAR","tipo":"soundlike"},"record_4":{"codigo":"20100235","primerapellido":"ANALZ","segundoapellido":"NAH ","nombres":"ROSA ELENA ","curp":"AANR810317MYNLHS02","tipo":"soundlike"},"record_5":{"codigo":"1901128","primerapellido":"ARGAEZ","segundoapellido":"TUN","nombres":"ROSA DEL CARMEN","curp":"IGNORAR","tipo":"soundlike"},"record_6":{"codigo":"1901134","primerapellido":"BAESA","segundoapellido":"CEBALLO","nombres":"ROSA MINELIA","curp":"IGNORAR","tipo":"soundlike"},"record_7":{"codigo":"1300047","primerapellido":"BASTO","segundoapellido":"AKE","nombres":"ROSA BEATRIZ","curp":"","tipo":"soundlike"},"record_8":{"codigo":"1901819","primerapellido":"BASTO","segundoapellido":"CAM","nombres":"MARIA ROSARIO DEL SOCORRO","curp":"IGNORAR","tipo":"soundlike"},"record_9":{"codigo":"1600206","primerapellido":"CANCHE","segundoapellido":"PECH","nombres":"CARMINIA DEL ROSARIO","curp":"","tipo":"soundlike"}}

And the this error:

TypeError: this[("text" + "Handler")] is not a function

Any idea? any help?


Thanks,
