I'm trying to get data from sampledata.json

**Errors:**

1. `{{sampledata}}` displaying `[object Object]`
2. `{{sampleDataModel.Title}}` ERROR TypeError: Cannot read property 'Title' of undefined

**sampledata.json:**

```
  {
    "isSuccessfull": true,
    "Model": [
        {
            "SampleDataModel": [ 
                {
                  "Title": "SampleData 1",
                  "Description": "Description."
                }
            ],

            "SampleDetailModel": [
            {
                "name": "Donald Trump",
                "id": "111",
                "country": "USA"
            }
           ]
        }
      ]
    }

```

**sampledata.services.ts :**

```
    import { Injectable } from '@angular/core';
    import { Http, Response } from '@angular/http';
    import {Observable} from 'rxjs/Rx';
    import 'rxjs/add/operator/map';

    @Injectable()
    export class SampledataService {

      private _url = 'assets/data/sampledata.json'

      constructor(private _http: Http) { }

      getData(){

        return this._http.get(this._url)
          .map((resSampleData: Response) => resSampleData.json());
      }

    }

```

**sampledata.component.ts:**

```
import { Component, OnInit } from '@angular/core';
import { SampledataService } from '../sampledata.service'

@Component({
  selector: 'app-sampledata',
  templateUrl: './sampledata.component.html',
  styleUrls: ['./sampledata.component.css']
})
export class SampledataComponent implements OnInit {

  sampledata = [];
  sampleDataModel = [];
  sampleDetailModel = [];

  constructor(private _sampledataservice: SampledataService) { }

  ngOnInit() {  

    this._sampledataservice.getData()
      .subscribe(resData => { 
        this.sampledata = resData;
        this.sampleDataModel = resData.Model.SampleDataModel;
        this.sampleDetailModel = resData.Model.SampleDetailModel });

  }

}

```

**sampledata.component.html:**

```
<h3>{{sampledata}}</h3>
<p>{{sampleDataModel.Title}}</p>
<p>{{sampleDetailModel.name}}</p>

```

**My Questions is:**

How do I get these values to display?

If anyone of you have any idea on how to solve this issue, please help to suggest the solutions to me, thank you.
