I'm not entirely sure what you mean by binding methods to the instance. 
Do you mean you need to dynamically add methods to a specific instance? 
Or that you need to add methods to a class, such that they can be invoked 
on specific instances? For the latter, just do:

TestClass.test_foo = test_foo

For the former, try:

tc = TestClass()
tc.test_foo = types.MethodType(test_foo, tc)
