<s>[INST] # Overview

I have a problem with my angular application where my ngModel is not updating the UI after changing the object. 

# Problem
The bug is that the component is not showing the updated values after calling `updateFunction` method.

```typescript
// My Component 
import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, Validators } from '@angular/forms';

@Component({
  selector: 'app-my-component',
  template: `
    <form [formGroup]="formGroup">
      <input formControlName="name" type="text">
    </form>
  `
})
export class MyComponent implements OnInit {
  formGroup: FormGroup;

  ngOnInit(): void {
    this.formGroup = new FormGroup({
      name: new FormControl('John Doe', Validators.required)
    });
  }

  updateFunction(): void {
    this.formGroup.get('name').patchValue('Jane Doe');
    this.formGroup.markAsDirty();
  }
}
```

After calling `updateFunction`, even though the value of the form control has been updated, the view is not updated with the new value. 

# Attempted Solution
I have tried using the `patchValue` method and also `markAsDirty` but it has not worked.

# Questions
Why is my component's UI not updating even after using `patchValue` and `markAsDirty`?[/INST]
