TypeError:v.context.$implicit不是函数

我是Typescript的新手.我已经3天了.我想从Firebase访问数据.我访问并列出.当我想用(Click)="item()"传递给另一个页面时,我收到错误.我在哪里做错了.

数据api.service.ts

import {Injectable} from '@angular/core';
import {Http,Response} from '@angular/http';

import 'rxjs';
import {Observable} from 'rxjs/Observable';
@Injectable()

export class DataApi {


 private url = 'https://ionic2-9dc0a.firebaseio.com/.json';   // https://ionic2-9dc0a.firebaseio.com

 currentphone : any = {};
constructor(private http:Http){
}
  getAdress(){
    return new Promise(resolve =>{
      this.http.get(`${this.url}`) 
      .subscribe(res => resolve(res.json()))
    });
  }





  }

about.ts

import { Component } from '@angular/core'; 
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import {DataApi} from '../../app/shared/shared';
import {Http, HttpModule} from '@angular/http';


import  {TeamsPage} from '../teams/teams';

 @IonicPage()
 @Component({
 selector: 'page-about',
 templateUrl: 'about.html',
  })
 export class AboutPage {

 names: any;
 constructor(public navCtrl: NavController, public navParams: NavParams, 
 public dataApi:DataApi, public http:Http) {

 }

 item(){
    this.navCtrl.push(TeamsPage);
  }

 ionViewDidLoad(){
    this.dataApi.getAdress().then(data => this.names= data[0]);
    console.log("willloaded");


   }


}
