row().child().show()

I'm using row().child(<some data>).show() to show some child data and row().child().hide() to hide the data.

.child(some data) calls an AJAX method that I only want to have to call once if the row is expanded multiple times.

row().child(<some data>).show() displays the data every time but it also reloads the AJAX method.

Unfortunately, row().child().show() does not display the data the second time, although row.child() (as seen in a console.log) does contain the data I want to display.

What am I missing?
