Is skuid.utils.delayInputCallback() any method in skuid.utils API?

I want my users to notice right away when they are entering values in a field in a table component. I want to show number of remaining characters that can be enter in that field.

I got some similar code here: https://community.skuidify.com/skuid/topics/magic_real_time_error_warning_rendering_using_javascript…
In this a found a method

skuid.utils.delayInputCallback, but I didn't find this method in skuid.util API.<br>Please let me know how to implement the above funtionality i.e; to count number of remaining charecters that can be entered in the field.<br>

This method has been added to the skuid.utils API docs:
