I tried to edit a woocommerce add_action, but it does not work. Dont know whether this is the right way to customize a woocommerce action?

What I did:

added following code into woocommerce functions.php

global $woocommerce;
$arr=$woocommerce->payment_gateways->get_available_payment_gateways();
remove_action( 'woocommerce_email_before_order_table', array($arr['bacs'] , 'email_instructions' ), 10, 2 );
add_action( 'woocommerce_email_before_order_table', array( $arr['bacs'], 'newemail' ), 10, 2 );
function newemail( $order, $sent_to_admin ) {

    	if ( $sent_to_admin ) return;

    	if ( $order->status !== 'on-hold') return;

    	if ( $order->payment_method !== 'bacs') return;

		if ( $description = $arr['bacs']->get_description() )
        	echo wpautop( wptexturize( $description ) );

		?><h2><?php _e( 'FuckingDetails', 'woocommerce' ) ?></h2><ul class="order_details bacs_details"><?php

		$fields = apply_filters('woocommerce_bacs_fields', array(
			'account_name' 	=> __( 'Account Name', 'woocommerce' ),
			'account_number'=> __( 'Account Number', 'woocommerce' ),
			'sort_code'		=> __( 'Sort Code', 'woocommerce' ),
			'bank_name'		=> __( 'Bank Name', 'woocommerce' ),
			'iban'			=> __( 'IBAN', 'woocommerce' ),
			'bic'			=> __( 'BIC', 'woocommerce' )
		));

		foreach ($fields as $key=>$value) :
		    if(!empty($arr['bacs']->$key)) :
		    	echo '<li class="'.$key.'">'.$value.': <strong>'.wptexturize($arr['bacs']->$key).'</strong>';
		    endif;
		endforeach;

		?><?php
    }

Action removes, but then When I add my new customized action it does not trigger. Also it has problems with other payment gateways
