Aurelia customAttribute not working

Question

I have a problem with customAttribute. I want to use it to plug in jquery-ui datepicker. Idea taken from here: http://www.danyow.net/jquery-ui-datepicker-with-aurelia/

However it looks like it is not working at all. I have tried to debug the application and it looks like [email protected] is not fired at all. However the file itself is being requested from the server. The worst thing is that I had it working yesterday evening, but today morning ...

I have created simple example in my fork of skeleton application: https://github.com/Exsilium122/skeleton-navigation so it is ready to be cloned and run for troubleshoot.

The most important two files:

---

welcome.html

<template>
  <require from="./resources/datepicker"></require>
  <input id="myDate" datepicker="datepicker" value.bind="timestamp | dateFormat"/>
</template>

---

datepicker.js

import {inject, customAttribute} from 'aurelia-framework';
import 'jquery-ui';
import 'jquery-ui/themes/cupertino/jquery-ui.css!';

@customAttribute('datepicker')
@inject(Element)
export class Datepicker {
    constructor(element) {
        this.element = element;
    }

    attached = () => {
        console.log("attached Datepicker");
        $(this.element).datepicker({
            dateFormat: 'mm/dd/yy'
        }).on('change', e => fireEvent(e.target, 'input'));

    }

    detached = () => {
        console.log("detached Datepicker");
        $(this.element).datepicker('destroy').off('change');
    }
}

function createEvent(name) {
    var event = document.createEvent('Event');
    event.initEvent(name, true, true);
    return event;
}

function fireEvent(element, name) {
    var event = createEvent(name);
    element.dispatchEvent(event);
}

and the console is clean:

Answer 1

attached = () => { needed to be changed to attached() {, as discussed in the gitter.

Corresponding changes were required for the detached method.

This question can be closed- the OP got the issue resolved in the aurelia gitter.

Answer 2

just did a:

• clone from your repo
• npm install jspm
• npm install
• jspm install -y

and guess what. it works :)
