How set value for filter?

roscez

I'm have my input and button

<input id="gridSearch" type="text" />
<button id="filter" class="btn btn-default">Go</button>

And my table

    $.fn.dataTable.ext.legacy.ajax = true;
    var grid = $("#gridCustomer").DataTable({
        "language": {
            "sProcessing": '<img src="/Scripts/loadingBgBlack.GIF" /> Loading...'
        },
        "bFilter": false,
        "bLengthChange": false,
        "processing": true,
        "serverSide": true

How set filter value for my grid ?

    $('#filter').click(function (e) {

        var searchValue = $("#gridSearch").val();

    });
