1. Bug Fix events on inner elements overriden by the existence of a cust… …

   …om render function
   
   This addresses the following scenario:
   
   I am adding existing (non-rendered to the DOM) TRs to DT with events
   attached to their children.
   
   I want a custom render function for providing filter and sort data, but
   not display data. If there is a custom render function it overrides all
   data including display data and overwrites the original cell content
   (even if the data is unchanged) which results in the fact that events
   of children inside the cell are lost.
   
   This could be prevented if the render function can signal DT that it
   doesn’t want to override the data and it wants to use the original
   display data. Returning undefined is a good signal.
   
   To address this issue, before overwriting the innerData of a cell using
   the display data from the custom render function you can check whether
   the data is null (undefined gets turned into null at this point).
   
   And for all intents and purposes there is no point in overwriting the
   cell content with null or undefined. Of course overwriting it with an
   empty string ”” works correctly and would replace the display data (so
   does null).
