Json binding in an array of checkboxes

Question

I have an array of checkboxes coming from a collection.

See below:

<div class="form-group">
    Select days in a week :
    <td class="even" *ngFor="let item of dayList">
    <input value="{{item.check}}" type="checkbox" checked="item.check" formControlName = "selectedDays">  {{item}}
   </div>

formControlName I am set as selectedDays.

I need to generate JSON object for the selected checkbox values.

Currently, i am getting boolean value in selectedDays. But I am supposed to get an array of checked values in an array inside JSON object.

this.dayList = ['Sun', 'Mon', 'Tue','Wed',"Thu","Fri","Sat"];

JSON Object looks like below, please note the value of selectedDays, it is supposed to be "Sun, Mon" based on selection, but it is showing as true.

 Object
    date
    :
    "2"
    day
    :
    "Mon"
    hour
    :
    "3"
    minute
    :
    "3"
    schedulerjobtype
    :
    "Daily"
    selectedDays
    :
    true
    useCase
    :
    "UC 2"
    zone
    :
    "Zone 3"

How can I implement this?

any idea why downvoted?

Use [(ngModel)] in place of value

 <input [(ngModel)]="item.check" type="checkbox" checked="item.check" formControlName = "selectedDays">

this is showing the checkboxes now, but still, the JSON object value shows true, i am expecting array or comma separated values.
