Hi, 

I need to add a button inside (every row) in one2many field in Purchase order line. 

Eg:

Using Icon

<button name="open_view_wizard" string="Price" type="object"

icon="fa fa-tasks" attrs="{'invisible':[('product_id','=', False)]}" />

by using this it will add icon in purchase line.

But, if i add without icon it will insert the button like text

I want to add a button without icon..

can anyone know how to resolve this...
