[Accordion][IOS] Plugin doesn't work

Hi @triniwiz,

The plugin show this:

The problem come from this line at the init time itemHeaderTemplate is undefined and for that the plugin set the json data to the view instead of the template for that we see [object object]

I tried setTimeOut on the constructor but it doesn't solve it but if I did that it work for the header and need to be set for all templates! :

this._defaultItemHeaderTemplate = {
            key: 'default',
            createView: () => {
                
                return Builder.parse(`<StackLayout id="headerTemplate" backgroundColor="green" >
                <Label text="{{headerText}}"/>
            </StackLayout>`, this);
            }
        };

What can we do on this scenario ?

my code is same as the doc, here it:

<accordion:Accordion height="100%" items="{{items}}" allowMultiple="false" selectedIndexes="{{selectedIndexes}}">

                <accordion:Accordion.headerTemplate>
                    <StackLayout id="headerTemplate" backgroundColor="green" >
                        <Label text="{{headerText}}"/>
                    </StackLayout>
                </accordion:Accordion.headerTemplate>


                <accordion:Accordion.itemHeaderTemplate>
                    <GridLayout backgroundColor="blue">
                    <Label height="100%" text="{{title}}"/>
                    </GridLayout>
                </accordion:Accordion.itemHeaderTemplate>

                <accordion:Accordion.itemContentTemplate>
                    <StackLayout backgroundColor="orange">
                    <Image height="200" decodeWidth="200" decodeHeight="200"  src="{{image}}"/>
                    <Label text="{{text}}"/>
                    </StackLayout>
                </accordion:Accordion.itemContentTemplate>


                <accordion:Accordion.footerTemplate>
                    <StackLayout backgroundColor="yellow">
                    <Label text="{{footerText}}"/>
                    </StackLayout>
                </accordion:Accordion.footerTemplate>
            </accordion:Accordion>

export class HowToViewModel extends Observable {

    selectedIndexes = [0]
    items: ObservableArray<any>

	constructor() {
		super();
        this.items = new ObservableArray([
            {
              title: '1',
              footer: '10',
              headerText: 'First',
              footerText: '4',
              image: 'http://placehold.it/120x120&text=First',
              items: [
                {image: '~/images/a9ff17db85f8136619feb0d5a200c0e4.png', text: 'Stop'},
                {
                  text: 'Drop',
                  image: '~/images/shazam.jpg'
                }]
            },
            {
              title: '2',
              footer: '20',
              headerText: 'Second',
              footerText: '5',
              image: 'http://placehold.it/120x120&text=Second',
              items: [{
                text: 'Drop',
                image: '~/images/batman.jpg'
              }, {text: 'Drop', image: '~/images/f29.png'}]
            },
            {
              title: '3',
              footer: '30',
              headerText: 'Third',
              footerText: '6',
              image: 'http://placehold.it/120x120&text=Third',
              items: [{text: 'Drop', image: '~/images/strider.png'}, {
                text: 'Drop',
                image: '~/images/f29.png'
              }]
            }
          ]);
	}

}

Start in packages/nativescript-accordion/common.ts at line 129 and reproduce the issue with the XML and ObservableArray example in the report. Trace when itemHeaderTemplate is initialized relative to the template bindings; done means the item header and other templates render their bound views on initialization without requiring setTimeout.
