Change the string of an inherited field

Question

I am using odoo 9, and I have inherited the invoicing module. In the python code I tried to change the name of one of the invoice.lines fields, basically the quantity. The change is reflected in the model when I go and check the DB structure. However, the form is viewed with the base model field string which is "Quantity"! The xml file does not give any string name to the field, so it does not override. I don't know what is wrong there!

I also wanted to change the string of an inherited field.
To do so, you can just re-declare the field with the attributes you want to override. The rest is taken from the base class:
class ModelA(models.Model):
_name='module.model_a'
my_field = fields.Many2one('product.product', string='MyField')
class ModelB(models.Model):
_name='module.model_b'
_inherit = 'module.model_a'
my_field = fields.Many2one(string='NewNameDisplayName') # The rest is taken from ModelA

Do not forget to add in your module, in file __openerp__.py:
*'depends': [ 'account', ]*

Thank you Mounir and zbik,
I have already added account as a module on which the one I am implementing depends:
'depends':['account']
has already been done.
As for the attributes I am just wondering why it couldn't be done from the python code?
The thing that is surprising me is that in the settings, under the database structure, the field string in the model is correctly showing the string I have given it in the python code. However, in the form it just views it with the string in the base mode
