Error when creating view - [dbo].[someFunction] is not schema bound

Question

I get this error when creating a view: "Cannot schema bind view 'dbo.viewStock'. 'dbo.GetStockCurrentQuantityByProduct' is not schema bound."

BACKGROUND: What I actually want to achieve is improve the speed of a query that retrieves Product Id / Current Stock. The current stock is calculated by a function that counts the units in/units out for a specific product ('dbo.GetStockCurrentQuantityByProduct'). I am exploring a possible solution - creating an indexed view to hold product Ids and current stocks, so I can select directly from it for faster query execution:

    CREATE VIEW [dbo].[viewStock] with schemabinding
    as 
    SELECT P.ProductId, 
    dbo.GetStockCurrentQuantityByProduct(P.ProductId) AS Quantity 
    FROM dbo.Product 

When I execute this, I get the error:

    Cannot schema bind view 'dbo.viewStock'. 
'dbo.GetStockCurrentQuantityByProduct' is not schema bound.

See the SCHEMABINDING option of CREATE FUNCTION or ALTER FUNCTION
