Recalculate taxes on programatically created invoice in Odoo 12

In odoo I have created an invoice with correct invoice line items ( including tax ). I am using a node module for this which calls the /web/dataset/call_kw endpoint in odoo.

My problem is, that the tax on the invoice is not updated after adding the line items. It remains 0. Can I force the recalculation of the invoice or must I calculate the total tax and set it on the invoice programatically?

I have tried to call the method 'button_reset_taxes()' on the account.invoice object via the web api, but failed. Error: account.invoice has no attribute button_reset_taxes.
