Ionic 5, Ionic Checkbox So Late Behavior

I tried to bind checked attribute value on ion-checbox but the behavior is a bit late. On my ts file I have an array variable user_id and on my checkbox list i put an action to fil

Solution 1:

Please refer to Ionic documentation on ion-checkbox

using the (click) to capture the action on a checkbox is wrong.

I suggest you use (ionChange) event to trigger your addUser() function.

With [(checked)] binding, it will create an automatic sync between your actions and the values you save.
