Render function is called for all rows even when deferRender option is set to true

Pavel V.

This is causing problems for big data when complex mapping is done in render function. Is it possible to execute it lazy (only for rows currently disaplyed)?

Here is jsfiddle example with deferred render:

Check out console.log messages. Even though only 10 items rendered on first page, render is called for whole dataset.
