I have a problem in changing the names for odoo addon modules. I've tried with xpath, attributes, but I just can't get it to work.

<xpath expr="//field[@name='manager_id']" position="attributes">
    <attribute name="string">New Field Label</attribute>
</xpath>

<field name="manager_id" position="attributes">
    <attribute name="string">New Field Label</attribute>
</field>

There must be a  way to change the field labels? And is there a way to change it so that it changes in every view the field is used?

EDIT:

code that I tried:

<record model="ir.ui.view" id="view_hr_res_company_form">
	<field name="inherit_id" ref="base.view_company_form" />
	<field name="model">res.company</field>
	<field name="arch" type="xml">
		<xpath expr="//form/sheet/notebook/page/field[@name='company_registry']" position="attributes">
			<attribute name="string">Matična številka</attribute>
		</xpath>
		<xpath expr="//field[@name='vat']" position="after">
			<field name="account_no"/>
			<field name="obcina"/>
			<field name="dejavnost"/>
		</xpath>
	</field>
</record>
