Grid Selection Problem - remote filter and remote sort

Hello,

I have a problem with grid's selections using remoteSort or remoteFilter.

The selectionchange event is not fired when i sort or filter the store. This problem is only in extjs 5.1, in 5.0 its fine.

Fiddle example: http://ift.tt/1Ib9hOc

The btn "select to enable" shoud be enable when the grid has one or more itens selecteds.

tkhs
