It suffices to use square brackets filled with the indices (as integers, not as x or y) of the component you are interested in:
sage: domega[0,1]
-2*y
Notice that the result is a coordinate function. To get the underlying symbolic expression (to be used for instance in some integration) you have to apply the method expr() atop of it:
sage: domega[0,1].expr()
-2*y
