Filter Grid by column filter from Javascript

is it possible to set a filter and refresh the Koolgrid from Javascript only? I tried this as shown below, the width of the column changes (for testing, so I'm right with the reference to my objects), but the Data shown in the grid is not changing. I tried several filters. I also tried several settings for the grid in PHP, as grid>AllowFiltering with no effect.
Thanks a lot.
<script type="text/javascript">
function foo()
var mastertable = grid.getMasterTable();
var columns = mastertable.getColumns();
var column = columns[5];
// the column shows m for male, w for female
<div class="divDefForm">
<button type="button" onclick="foo()">Filter Me!</button>
