[184328] Filter on a computed column based on a date value does not work

- Description:
When the column binding is referenced in _javascript_ _expression_, we do not convert its value to _javascript_ value. This lead to two problems:

1. Because the data set row values are converted to _javascript_ value during evaluation, this leads to the inconsistency of behavior.

2. For all column binding values referenced in _javascript_ _expression_, some native _javascript_ object functions(say, those for NativeDate) would not be usable.

Fix the bug by convert column binding values to _javascript_ data type value once they are used as _javascript_ object. Meanwhile keep the column binding value that returned through DtE API call as java data type. The unit test is added.

- Tests Description:
Unit Test.
