Passing option value onChange of Select input

I am trying to pass a value from the <option> of my <select> input to my livewire controller component and echo the value.

Livewire Blade View Component:

{!! Form::select('goals',$goals_plucked,null,[
    'placeholder' => trans('classes.backend.forms.select_goals'),
    'class' => 'custom-select',
    'id' => 'goals',
    'wire:change' => "goals(this.val)",
]) !!}

This get's me an output of null in my Livewire Controller Component

Livewire Controller Component

public $goals;

public function goals($goals)
{
    dd($goals);
}

After watching some tutorials. I also tried using 'wire:change' => "goals($event.target.value)", which gave me an error of Undefined variable $event, obviously because it was not defined in main controller. I am not sure what am I doing wrong here.

What I am trying to do: Trying to create a flow just like select country then select state and then select city. via livewire. Before selecting a country the inputs of the select state and city won't be visible
