Radio button is not getting checked in angular 2

I have created two radio button for gender, I want to display radio button checked that was previously selected.

I have added below code in Template

<div class="form-group">
    <label>Gender</label>

    <div id="input-type">
        <label class="radio-inline">
            <input type="radio" formControlName="gender" [name]="'gender'" [value]="'male'"/> Male
        </label>
        <label class="radio-inline">
              <input type="radio" formControlName="gender" [name]="'gender'" [value]="'female'"/> Female
        </label>
    </div>
</div>

I have added below code in Component.

console.log(this.gender);  // I am getting 'male' here.
this.editProfile = new FormGroup({
     gender: new FormControl(this.gender || null)
});

Other value of the form is getting displayed but radio button is not getting checked.

I have found other solution. We can use below code

<div class="form-group">
    <label>Gender</label>
      <div id="input-type">
          <label class="radio-inline">
              <input type="radio" [checked]="editProfile.value.gender == 'male'" formControlName="gender" value="male"/> Male
          </label>
          <label class="radio-inline">
                <input type="radio" [checked]="editProfile.value.gender == 'female'" formControlName="gender" value="female"/> Female
          </label>
      </div>
</div>

You can write it like 

  <form [formGroup]="form" (ngSubmit)="onSubmit(form.value)">

    <label class="radio-inline">
            <input type="radio" formControlName="gender" [name]="'gender'" [value]="'male'"/> Male
        </label>
        <label class="radio-inline">
              <input type="radio" formControlName="gender" [name]="'gender'" [value]="'female'"/> Female
        </label>
     <button type="submit" [disabled]="form.invalid">Submit</button>

    {{form.value|json}}
  </form>

It should work for you

As you are using Reactive Forms you can omit name attribute on input and because you are setting string value to input so you have to use value="male" instead of [value]="'male'".

<div class="form-group">
  <label>Gender</label>

  <div id="input-type">
    <label class="radio-inline">
        <input type="radio" formControlName="gender" value="male"/> Male
    </label>
    <label class="radio-inline">
          <input type="radio" formControlName="gender" value="female"/> Female
    </label>
  </div>
</div>
