Here I have custom post type called products and it's taxonomy is product_categories . What I need is whenever I add the post in products , I need to call function1, when I update the post then I need to call function2 . How to do this?

I have searched on google and found this solution:

add_action('save_post', 'save_in_filter', 10, 2);
        function save_in_filter($post_id, $post){
          function1();  
        }


 function mynewproduct(){
    myfunction();
}

But what happens is when I click on add new post then suddenly the function1() execute , but what i need is function1 execute after inserting the data not before inserting the data.

When a post is added to products (post_type=products) i need to execute function1(). When a post is updated in products i need to execute function2(); Why post_updated,save_post function not working properly?

This is the original answer but it is little faulty, look below for the updated

You can use following approach.

The my_action_updated_post_meta is executed after the post insert or update is done:

// define the updated_post_meta callback
function my_action_updated_post_meta( $array, $int, $int ) {
    global $post;

    // see your updated post
    print_r($post);

    // make your action here...
    die('after update');
};

// add the action
add_action( 'updated_post_meta', 'my_action_updated_post_meta', 10, 3 );

Here's the function's documentation page.

Update

I have notice that the above response is a little faulty - the updated_post_meta action (for post updates) is fired also when opening post for edition in the admin panel (since the _edit_lock is set then), even when no real change is made then.

So I changed the approach.

I use a global variable $my_updated_flag to know that a "real" change has been made. I set this variable to "1" by post_updated action. So if $my_updated_flag == 1 we know that this is not just a _edit_lock change. To differentiate post insert and update action I check the $post->post_status == 'draft' since new posts have "draft" status at this stage.

$my_updated_flag = 0;

// define the updated_post_meta callback
function action_updated_post_meta( $meta_id, $post_id, $meta_key, $meta_value = '' ) {
    global $post, $my_updated_flag;

    if ($my_updated_flag == 1) {
        if ($post->post_status == 'draft') {
            die('post_inserted');
        } else {
            die('post_updated');
        }
        $my_updated_flag = 0;
    }
};
add_action( 'updated_post_meta', 'action_updated_post_meta', 10, 4 );

function action_post_updated( $array, $int, $int ) {
    global $my_updated_flag;
    $my_updated_flag = 1;
};
add_action( 'post_updated', 'action_post_updated', 10, 3 );

have a look at the post_updated hook for example..

// Hook to all private or public post types updating
add_action( 'post_updated', 'my_function' );    

function my_function( $post_id ){

    $post_status = get_post_status( $post_id );

    switch ( $post_status ) {
        case 'draft':
        case 'auto-draft':
        case 'pending':
        case 'inherit':
        case 'trash':
            return;

        case 'future':
        case 'publish':
        case 'private':
            // continue

    }

   'do something; 
}
