yerlix on "custom message on quick edit"

On my site, I check if an array doesn't exceed 3 values. Now I want to doe this as well on the quick edit form.

So far, I get the message only when I refresh the browser.

The code I use when I save the quick edit:

if ( array_key_exists( 'speciality', $_POST ) ){
			    // update_post_meta( $post_id, 'med-spec', $_POST[ 'speciality' ] );
			    // inlezen specialiteiten
		        $specs = preg_split("/[\s,]+/", $_POST['speciality']);

		        // check of er maximum 3 ingevuld zijn
		        if (count($specs) < 4){
		            update_post_meta( $post_id, 'med-spec', $_POST[ 'speciality' ] );
		        } else {
		            $_SESSION['my_admin_notices'] = "<div class='error'><p>Maximum 3 specialiteiten!</p></div>";
		            return false;
		        }
			}

The code above checks if the array is maximum 3 values long and puts a message in the session when it is not.

On my page I recall the session:

function my_admin_notices(){
        var_dump($_SESSION['my_admin_notices']);
        if(isset($_SESSION['my_admin_notices'])) {
            print  $_SESSION['my_admin_notices'];
        } else {
           $value = '';
        }
        unset($_SESSION['my_admin_notices']);
    }
    add_action( 'admin_notices', 'my_admin_notices' );

But this shows the message only on refreshing the browser.

Is there a hook for this? Or must this be done through javascript?
