Angular 2模板的访问控制值

Question

是否可以从我的模板中访问channel_header控件    这个=＆gt; _form.controls [＆＃39;头＆＃39]。对照[I] .controls.channel_header

import { FormBuilder, Validators, FormArray } from '@angular/forms';

constructor(private _fb: FormBuilder) 
ngOnInit() {
  this._form = this._fb.group({
       headers: this._fb.array([
           this._fb.group({
               channel_header: ['', Validators.required],
               data_option: ['', Validators.required]  
           })
       ]);
  });
}
