Angular 6 td 标签中的复选框不触发（更改）

Question

I am working on a angular project where I wish to check on the dynamic generated checkbox which are being checked however the (change) handler doesn't seems to fire

tickets.html

<tr *ngFor="let ticket of tickets; let i = index">
<td *ngIf="memberView">
<div class="custom-checkbox">
   <input type="checkbox" (change)="memberChange($event,ticket)" id="memberEvent{{i}}" class="custom-control-input -input-check" value="">
</td>
</tr>

tickets.ts

memberChange(event,ticket){
    console.log('onchange',ticket);
}

however the logging doesn't seems to fire at all, could someone help me with it

Answer 1

Attribute value of the checkbox is not binded with any value

<tr *ngFor="let ticket of tickets; let i = index">
  <td *ngIf="memberView">
  <div class="custom-checkbox">
    <input type="checkbox" (change)="memberChange($event,ticket)" id="memberEvent{{i}}" class="custom-control-input -input-check" [value]="ticket">
  </div>
  </td>
</tr>
