inregularity in attrs odoo10

Question

Hello friends I have a button in odoo which I want to be invisible when the 3 conditions are met:

<button class="oe_highlight"  name="formview" type="object" string="Pagar" attrs="{'invisible':['|',('status_inv', '=',2),('validate_cheque', '=',False),('pay', '=',True)]}"/>

I have the invisible attribute in this way but it does not behave well.

if I replace it | by & odoo gives an error finally what I want is that it behaves like the AND operator if the 3 is fulfilled that is invisible
