October CMS | How to get a property value from from component installed on specific page?

I created my component with an option "perPage", that acept an number and set the limit of works displayer per page...

public function defineProperties()
    {
        return [
            'perPage' => [
                'title' => 'Number os works per page',
                'description' => 'How many works do you want to display per page?',
                'default' => 9,
                'validationPattern' => '^[0-9]+$',
                'validationMessage' => 'Only numbers allowed'
            ],
            'sortOrder' => [
                'title' => 'Order of Works',
                'description' => 'How do you want to order the actors',
                'type' => 'dropdown',
                'default' => 'newest',
            ],
        ];
    }

It work's great with GET implementation... but on my project I need to implement AJAX everywhere, so I need to load pages via AJAX, and I need to know what the number was setted on a component... How I can get this number?

//my layout code
function onOpenWorkList()
{

    $this['works'] = Category::where('slug', input('slug'))->first();

    $this['categories'] = Category::all();

    $this['active_category'] = input('slug');

    $this['perPage'] = "";  // HERE IS THE CODE

    return [
        '.home_categories' => $this->renderPartial('work_list_categories_post'),
        '.container' => $this->renderPartial('work_list')
    ];
}
