Toggle Radio button not working in reactive form - angular 8 - angular-reactive-forms

Question

I'm using reactive form in angular 8, and have a gender toggle radio button.
The toggle radio button don't return the value of selected.
html code
<form id="sb-signup-form" method="post" novalidate="" [formGroup]="registerForm" (ngSubmit)="register($event)">
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-primary active">
<input id="male" type="radio" class="custom-control-input" value="male" name="gender" formControlName="gender"> Male
</label>
<label class="btn btn-primary">
<input id="female" type="radio" class="custom-control-input" value="female" name="gender" formControlName="gender"> Female
</label>
</div>
</form>
.ts code
registerForm: FormGroup;
ngOnInit() {
this.registerForm = this.formBuilder.group({
gender: ['male']
});
}
register(e) {
console.log(this.registerForm.value);
}
always the value of gender is 'male', which is the default value.

Answer 1

This is because of data-toggle="buttons", remove it you will see it work & add active class to label by writing a custom function.

Answer 2

Try Like this
In HTML file:
<form [formGroup]="form">
<label>
<input type="radio" value="Male" formControlName="gender">
<span>male</span>
</label>
<label>
<input type="radio" value="Female" formControlName="gender">
<span>female</span>
</label>
</form>
In the TS file:
form: FormGroup;
constructor(fb: FormBuilder) {
this.name = 'Angular2'
this.form = fb.group({
gender: ['', Validators.required]
});
}
