Modal not closing after filter

I have this JS file (Modal.js) which has the functions of show modal and close it after filter.

function showPleaseWait(msg, btnClicked) {
//recebo a mensagem e o botão clicado para saber se o form está valido
if (btnClicked != undefined && btnClicked.localName != "a") {
    var $form = $(btnClicked).parents('form');
    if ($form.length > 0 && $($form).valid()) {
        var msgPadrao = 'Aguarde...';
        if (msg == undefined) {
            msg = msgPadrao;
        }
        if (window.outerWidth < 577) {
            var pleaseWaitDiv = $('<div class="modal fade"  id="pleaseWaitDialog" data-backdrop="static" data-keyboard="false" role="dialog" aria-labelledby="basicModal" aria-hidden="true" tabindex="-1"><div class="modal-dialog"><div class="modal-content" style="background:transparent !important;border: 0px solid #ddd !important;"><div class="modal-body text-center row"><img src="/img/spinningwheel.gif" class="col-md-12 col-sm-12 col-xs-12 col-lg-12" /></div></div></div></div></div></div>');
        }
        else {
            var pleaseWaitDiv = $('<div class="modal fade" id="pleaseWaitDialog" data-backdrop="static" data-keyboard="false" role="dialog" aria-labelledby="basicModal" aria-hidden="true" tabindex="-1"><div class="modal-dialog"><div class="modal-content"><div class="modal-header"><h1>' + msg + '</h1></div><div class="modal-body text-center row"><img src="/img/progress_bar.gif" class="col-md-12 col-sm-12 col-xs-12 col-lg-12" /></div></div></div></div></div></div>');
        }


        pleaseWaitDiv.modal();
    }
} else {
    var msgPadrao = 'Aguarde...';
    if (msg == undefined) {
        msg = msgPadrao;
    }
    if (window.outerWidth < 577) {
        var pleaseWaitDiv = $('<div class="modal fade"  id="pleaseWaitDialog" data-backdrop="static" data-keyboard="false" role="dialog" aria-labelledby="basicModal" aria-hidden="true" tabindex="-1"><div class="modal-dialog"><div class="modal-content" style="background:transparent !important;border: 0px solid #ddd !important;"><div class="modal-body text-center row"><img src="/img/spinningwheel.gif" class="col-md-12 col-sm-12 col-xs-12 col-lg-12" /></div></div></div></div></div></div>');
    }
    else {
        var pleaseWaitDiv = $('<div class="modal fade" id="pleaseWaitDialog" data-backdrop="static" data-keyboard="false" role="dialog" aria-labelledby="basicModal" aria-hidden="true" tabindex="-1"><div class="modal-dialog"><div class="modal-content"><div class="modal-header"><h1>' + msg + '</h1></div><div class="modal-body text-center row"><img src="/img/progress_bar.gif" class="col-md-12 col-xs-12 col-sm-12 col-lg-12"/></div></div></div></div></div></div>');
    }

    pleaseWaitDiv.modal();
}
}

function hidePleaseWait() {
$('#pleaseWaitDialog').modal('hide');
}

I call them after clicking search.

 var data;

/* Busco os dados filtrados pelo range da data */
function Buscar() {
    showPleaseWait();
    var data = getParameterByName('data');
    var dataInicio = $('#datainicio').val();
    var dataFinal = $('#datafinal').val();
    $('#dashboard').focus();
    DrawonLoad(dataInicio, dataFinal, "bottom", 300, "center", 10, data);
    buscaAtosPraticados();
    DrawonLoad2(dataInicio, dataFinal, "bottom", 300, "center", 10, data);
    buscaCertidoes();
    DrawonLoad3(dataInicio, dataFinal, "bottom", 300, "center", 10, data);
    buscaBalcaoCRT();
}
