javascript datatable filter not filtering

I am trying to filter my table by element.data. I have a dropdown list for the user to select the value and a submit button once they have finished. The table gets the initial data but when I select a value and click submit I get all of the values. The filter is not working at all.

Javascript filter

 $('#Product').on('change', function () {
    var count = 0;
    var value = this.value;

    $('#results-tbody tr').each(function () {

        var element = $(this);

        element.data('filters', element.data('filters').replace(/dropdown/g, ''));

        if (value !== 'All' && element.data("product").indexOf(value) === -1) {
            element.data('filters', element.data('filters') + 'dropdown');
        }
        count = count + hideOrShow(element);
    });
    setResultsCount(count);
});
$('#Changes').on('change', function () {
    var count = 0;
    var value = this.value;
    $('#results-tbody tr').each(function () {

        var element = $(this);

        element.data('filters', element.data('filters').replace(/dropdown/g, ''));

        if (value !== 'All' && element.data("oc").indexOf(value) === -1) {
            element.data('filters', element.data('filters') + 'dropdown');
        }
        count = count + hideOrShow(element);
    });
    setResultsCount(count);
});
