Filters are not available if reconfigure is applied on grid ext js 3.3.2

[shaikhmshariq]

I am using ext js 3.3.2 and once we apply reconfigure on grid with new store and columnmodel, filters are not visible as 'renderFields' function is only registered on 'render' event of grid.

As a work around I have also registered 'renderFields' on grid.getView()'s 'refresh' event. This works fine but as a author you might have better solution in terms of performance and coding pattern.

Thanks for providing such a nice plugin.
