How to make a VK post from the application?

Question

API

There is a VK application in which the user is given the opportunity to make a post on the wall.
I initialize vk.api: Next, I hang an event on the button, in which the following code:VK.init({apiId: '*******'})

console.log('share');

VK.api("wall.post", {
  "message": shareText,
  "attachments": attachment,
  "v":"5.87 "
});

And from this code only output to the console is performed, there is no reaction at all to the call to VK.api, there is not even an error in the console.
What am I doing wrong?

I connected this file to the header: https://vk.com/js/api/xd_connection.js?2and it all worked.
