How to pre-select and update checkboxes in angular 2+

I want to implement a checklist in angular. Some boxes have to be pre-checked based on an array in the ts file and the array has to be updated when a checkbox in checked: I am doing it like :

<div class='form-group que-box' *ngFor="let option of currentQuestion.options">
  <input type="checkbox" aria-label="Checkbox 1" [value]="option.text" name="checkBox" [(ngModel)]="optionsSelectedArray"/>
  <label for=''><span class="que"></span></label>
</div>

optionsSelectedArray contains the option Ids retrieved from server.

But it doesn't work.All the checkboxes come checked when the the division is rendered.
