gridApi.grid.refresh() no longer triggers custom filter function (after v3.1.1)

[bowen-cheng]

After upgrading from v3.1.1 to v3.2.1, when I call gridApi.grid.refresh() function to refresh the grid, the custom filter function (declared under columnDefs) is ignored.

By doing some experiments, I realize that the custom filter function is only triggered in v3.2.1 if we manually put text in the filter box.

This Plunker demonstrates the issue.

In this Plunker, the filter term is changed by clicking on the toggle button. The button also triggers refresh() function, this originally would cause the grid to re-evaluate custom filter function. Now it has lost its functionality.
