Filters in datables only working 1 time

Question

Good morning, stack overflow. I’ve been in trouble for a while where I can’t understand your reason.

I’m working with php datatables, where I do some custom filters. When I select for example 2 checkbox, and click on the button it works perfectly, soon after, if I try to change this filter, unchecking this box and selecting another, it does not filter, but sends the request normally.

Follow some requisition codes

$("#btnFiltrar").on('click',function() {
        if($(".chkTipoEducacional").is(':checked')) {
            var i =$('.chkTipoEducacional').attr('data-columns');
            var v =$('.chkTipoEducacional').val();
            dataTable.columns(i).search(v).draw();
            console.log(v);
        }
    });
    $("#btnFiltrar").on('click',function() {
        if($(".chkTipoComercial").is(':checked')) {
            var i =$('.chkTipoComercial').attr('data-columns');
            var v =$('.chkTipoComercial').val();
            dataTable.columns(i).search(v).draw();
            console.log(v);

        }
    });
    $("#btnFiltrar").on('click',function() {
        if($(".chkTipoProfissional").is(':checked')) {
            var i =$('.chkTipoProfissional').attr('data-columns');
            var v =$('.chkTipoProfissional').val();
            dataTable.columns(i).search(v).draw();
            console.log(v);
        }
    });

And some examples of php

if(!empty($requestData['columns'][8]['search']['value']) && !empty($requestData['columns'][11]['search']['value']) && !empty($requestData['columns'][12]['search']['value'])){
    $sql .= " AND issued_date BETWEEN '".$requestData['columns'][11]['search']['value']."' AND '".$requestData['columns'][12]['search']['value']."'";
}

if(!empty($requestData['columns'][2]['search']['value'])){
    $sql.=" AND licensed_version LIKE '".$requestData['columns'][2]['search']['value']."%' ";
}

Thanks in advance!
