Index will be removed

Question

I'm trying to simply change the length of a column within a table through SQL Server Management Studio, but receive a 'Validation Warning':

'MyTable' table
-Warning: The following schema-bound objects will be modified: 
 -View 'dbo.MyViewName': indexes and schema binding will be removed.

I remember from experience that if I actually go through with this, the binding will not be readded. In the past I've had to manually write a script to re-add the view. This doesn't seem right - why would it just remove it without re-adding it at the end of the operation?

It makes me think I don't have something set up correctly, or am going about this the wrong way - am I? Or is it 'correct' procedure to have to manually re-add things in this way after table changes are made?
