How come I keep running into the "is not a function" issue when trying to use the generateRequest function with Polymer's iron-ajax

Oops, it seems like there was an error: Uncaught TypeError: this.$.ajax.generateRequest is not a function. The issue seems to be in assets-ajax.html at line 23.

<dom-module id="assets-pull">
<style>
</style>
<template>

    <button on-click="setajax">Click me</button>

    <iron-ajax
            id="ajax"
            url=""
            handle-as="json"
            on-response="hresponse"
            debounce-duration="300">
    </iron-ajax>

</template>
<script>
    Polymer({
        is: "assets-pull",
        setajax: function () {
            this.$.ajax.url = "http://mytesturl.com/assets_all";
            this.$.ajax.params = {"userId":"1"};
            this.$.ajax.generateRequest();
        },
        hresponse: function(request) {
            console.log(request.detail.response);
            console.log(this.$.ajax.lastResponse);
        }
    });
</script>

I confirm that your code is successful. Just double-check that the iron-ajax element is correctly installed and imported.

Here's an example:

<link rel="import" href="../components/iron-ajax/iron-ajax.html">
<dom-module id="assets-pull">
  ...
</dom-module>
