我对将数据推入控件有点困惑，因为我在嵌套控件中使用控件我不知道如何将数据推入嵌套控件中这是我的 component.ts 代码

i am little confuse about push data into control because i using control inside nested control i have no idea how i push data inside the nested control this is my component.ts code

 mileStoneForm:FormGroup;
 constructor(private fb:FormBuilder) {
 this.mileStoneForm = this.fb.group({
  milestone:this.fb.array([])
 });


  createMilestone()
  {
  return this.fb.group({
    name:[''],
    date:[''],
    description:[''],
    value:[''],
    approval:[''],
    deliverable:this.fb.array([
      this.createMilestoneDeliverable()
    ])
  });
 }


   createMilestoneDeliverable()
  {
  return this.fb.group({
    title:[''],
    description:[''],
    excluded:['']
  });
 }


addNewDeliverable()
 {
return (this.mileStoneForm.get('milestone').get('deliverable') as 
FormArray).controls.push(this.createMilestoneDeliverable());
 }
