如何将对象属性绑定到 angular2 中的文本框

我是 Angular 的新手，我正在尝试绑定由模型对象中的文本框组成的表单。但我收到一个错误，如“未处理的承诺拒绝：模板解析错误：无法绑定到‘NgModel’，因为它不是‘输入’的已知属性”

我在谷歌上投入了大量时间，但问题仍然存在

下面是我的代码。

html：

    <div>
     <div class="col-sm-6 form-group">
        <label class="control-label">Project Name:</label>
        <input type="text" class="form-control" id="txtProjName" [(NgModel)]="projectFieldsdtl.PROJECT_NAME" >
    </div>

     <div class="col-sm-6 form-group">
        <label class="control-label">Project Manager Name:</label>
        <input type="text" class="form-control" id="txtProjManager" >
    </div>
    <div class="col-sm-6 form-group">
        <label class="control-label">Project Manager Email ID:</label>
        <input type="text" class="form-control" id="txtProjManagerMailID" >
    </div>
    </div>

app.module.ts

    import { NgModule }      from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { AppComponent }  from './app.component';
    import { FormsModule} from '@angular/forms';  
    import { HttpModule } from '@angular/http';
    import {SpotCheckStatusComponent} from './spotcheckstatus.component';

    @NgModule({
      imports:      [ BrowserModule ,FormsModule,HttpModule ],
      declarations: [ AppComponent,SpotCheckStatusComponent ],
      bootstrap:    [ SpotCheckStatusComponent ]
    })
    export class AppModule { }

projectFields.ts

        export class projectFields {
                public PROJECT_CODE:string;
                public PROJECT_NAME:string
                public PROJECT_MANAGER: string;
                public PROJECT_MANAGER_EMAIL_ID: string;    
        }

SpotCheckStatusComponent.ts

            import {Component,OnInit ,OnChanges} from '@angular/core';
        import {IMyDpOptions} from 'mydatepicker';
        import {HttpService} from './http.service';
        import { serviceLine } from './models/serviceLine';  
        import { projectFields } from './models/projectFields';  


        @Component({
          selector: 'my-app',
          styleUrls:['/css/home.css'],
          templateUrl:'./SpotCheckStatus.html',
          providers:[HttpService]

        })
        export class SpotCheckStatusComponent  implements OnInit
        {
             name = 'SpotCheckStatus'; 

             public projectFieldsdtl: projectFields[];  

          constructor(
            private httpService: HttpService
          ) {}

          ngOnInit(){

                  this.httpService.getProjectCode(serviceline).subscribe(
                  response=> {      

                    this.projectFieldsdtl=response[0];
                    },
                  error=> {
                      console.log("ERROR: ",error);
                      console.log(error.json()); //gives the object object
                  },
                  () => {
                      console.log("Completed");
                  }

                  );
            }
        }

最后 projectFieldsdtl 得到了如下对象：

    [{
    PROJECT_CODE:"9999"
    PROJECT_MANAGER:"shekat"
    PROJECT_MANAGER_EMAIL_ID:"[email protected]"
    PROJECT_NAME:"ABFL"
    }]
