Cannot trigger filter manually

[webbick]

Hi, I've read a lot of posts but cannot find an answer.
I created a link. When clicked on, some JS copies a string into the search field. I know that that's not enough to start the filter. I need to trigger it, but I cannot get it to work. Please help.

This is the JS of the link (id=onderwerp):

$('#onderwerp').click(function () {
    $('.form-control').val('some string');    // copy string to footable search field. THIS WORKS!
    $('.w-footable').trigger('footable_filter', { filter: $('.form-control').val() });
});

Ooo, wait, I was stuck in V2 code instead of V3...which is completely different!
Solved:
$('#onderwerp').click(function () {
var filtering = FooTable.get('.w-footable').use(FooTable.Filtering), filter = 'some string';
filtering.addFilter('status', filter, ); // no value after last comma means search in ALL columns
filtering.filter();
$('.form-control').val('some string');
});
