Primeng checkbox checked issue angular

In my working on angular 8 application where I am using primeng checkbox and I have some issue.Checkbox data is coming from db. So if status==0, I have to make it unchecked and if status==1, it should be selected even if load the table(default). I tried many ways and its not working. Can any one please point me the issue or any suggestions will be of great help.

 onStatusChange(id: number,status: number) {
        this.id = id;
        console.log('Id', id);
        console.log('Checked');
        this.status = status;
        console.log('Status', status);
        
    }
<p-checkbox [value]="text.id" [(ngModel)]="status" binary="true"  (onChange)="onStatusChange(TextID,status)"></p-checkbox>
Data from db is coming like this

{"Text":
[
  {"ID":"1","Name":"Text","textContent":"content1,"status":"1"},
  {"ID":"2","Name":"Text","textContent":"content1,"status":"1"},
  {"ID":"3","Name":"Text","textContent":"content1,"status":"0"}
]
}
Tried ternary if statement inside inside ngModel and ngModelChange

text.IsActive[text.IsActive==1?'true':'false'

I am getting the required data in onStatusChange to make it active or inactive for updating it to DB. But problem lies in making checkbox checked based on the selection while loading the data. Please help me.. stuck here for the last few days..

Instead of using the status directly as a number, you can map it to true or false with !!

1 => !!1 => true
0 => !!0 => false

If 1 or 0 should be a string then:

"1" => !!Number("1") => true
"0" => !!Number("0") => false

this allows you to use the values in the checkbox normally

I this you can use (ngModelChange) instead of (onChange). The code is given below =>
HTML

  <div>
    <p-checkbox 
      label="My CheckBox" 
      binary="true" 
      [(ngModel)]="showLinkedRisksOnly"
      (ngModelChange) ="myModelChanged($event)"
      >
    </p-checkbox>
    </div>
    <div>
    Value: {{showLinkedRisksOnly}}
    </div>

TS:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  showLinkedRisksOnly = true;
  myModelChanged($event){
    console.log($event);
  }
}

NOTE: You can check the code in STACKBLITZ.
