Passe a fuction to [canExit]

[AbigailAdjo]

Hello all ,
I have a verification to do before allowing the wizard to exit the current step and enter the next step,
I'm trying to passe a function to [canExit] but seems like the way I'm doing is the wrong one.
Can anyone help?

HTML :

<aw-wizard-step stepTitle="Identification" formGroupName="step1Validation"
[canExit]="canExitStep1($event)">

Typescript :

canExitStep1(direction: MovingDirection, forward: boolean, backward: boolean) {
switch (direction) {
case MovingDirection.Forwards : return forward;
case MovingDirection.Backwards: return backward;
}
}
