angular2 APIガイドで詳しく説明されているDynamicComponentLoaderを使用しています。

https://angular.io/docs/ts/latest/api/core/DynamicComponentLoader-class.html

次のようにコードをセットアップしました。

import {Page} from 'ionic-framework/ionic';
import { Component, View, DynamicComponentLoader, Injector } from 'angular2/core';
import { RouteParams } from 'angular2/router';

import { DataService } from '../../services/dataService';
import { Section } from '../../models/section';

@Component ({
    selector : 'itemView',
    template : '<div id="content"></div>'
})

export class ItemView {
    constructor (private dataService : DataService, private _routeParams : RouteParams, dcl: DynamicComponentLoader, injector: Injector) {
        var sectionid = this._routeParams.get ('sectionid');
        var categoryid = this._routeParams.get ('categoryid');
        var itemid = this._routeParams.get ('itemid');

        var views = {product: ItemproductView, dispensor: ItemdispensorView, signage: ItemsignageView, equipment: ItemequipmentView};

        if (categoryid !== null) {
            this.item = dataService.getCategoryItem (sectionid, categoryid, itemid);
        } else {
            this.item = dataService.getItem (sectionid, itemid);
        }

        dcl.loadAsRoot(views[sectionid], '#content', injector);
    }
}

@Component ({
    selector : 'itemproductView',
    templateUrl : 'build/components/item/item-product.html'
})
export class ItemproductView {
    constructor(private dataService : DataService, private _routeParams : RouteParams) {
        var sectionid = this._routeParams.get ('sectionid');
        var categoryid = this._routeParams.get ('categoryid');
        var itemid = this._routeParams.get ('itemid');

        this.item = dataService.getCategoryItem (sectionid, categoryid, itemid);
    }
}

@Component ({
    selector : 'itemdispensorView',
    templateUrl : 'build/components/item/item-dispensor.html'
})
export class ItemdispensorView {
    constructor(private dataService : DataService, private _routeParams : RouteParams) {
        var sectionid = this._routeParams.get ('sectionid');
        var itemid = this._routeParams.get ('itemid');

        this.item = dataService.getItem (sectionid, itemid);
    }
}

@Component ({
    selector : 'itemsignageView',
    templateUrl : 'build/components/item/item-signage.html'
})
export class ItemsignageView {
    constructor(private dataService : DataService, private _routeParams : RouteParams) {
        var sectionid = this._routeParams.get ('sectionid');
        var itemid = this._routeParams.get ('itemid');

        this.item = dataService.getItem (sectionid, itemid);
    }
}

@Component ({
    selector : 'itemequipmentView',
    templateUrl : 'build/components/item/item-equipment.html'
})
export class ItemequipmentView {
    constructor(private dataService : DataService, private _routeParams : RouteParams) {
        var sectionid = this._routeParams.get ('sectionid');
        var itemid = this._routeParams.get ('itemid');

        this.item = dataService.getItem (sectionid, itemid);
    }
}

Web ブラウザーにテンプレートが表示されますが、{{item}} がテンプレートにバインドされません。

どこが間違っているのかよくわかりません。助けていただければ幸いです。

ありがとう、
