Code Review

This pull request introduces a valuable feature for custom input counting in nz-input-wrapper. The implementation is well-structured, including documentation and a demonstration. However, I've identified a few areas for improvement in the core logic that could prevent potential runtime errors and improve code consistency. Additionally, there's an opportunity to streamline the test suite by removing a redundant test case. My feedback includes specific suggestions to address these points.
