You can use this    lt input type  checkbox   checked   record status   change   changeStatus record id  event   gt    And on your ts file   changeStatus id  e        var status   e target checked      this yourseverice changeStatus id  status  subscribe result   gt            if  status              this notify success this l  AddedAsKeyPeople             else             this notify success this l  RemovedFromKeyPeople                  Here  record is the model for current row and status is boolean value

Another approach is to use ngModelChange   Template    lt input type  checkbox  ngModel  ngModelChange   onChecked obj   event     gt    Controller   onChecked obj  any  isChecked  boolean     console log obj  isChecked          true    false      I prefer this method because here you get the relevant object and true false values of a checkbox
