Unexpectedly unwanted method is calling while another method calling

When I clicked the next button to move the next page, updatePolicyDetails() is calling. But at that moment, unexpected popup is showing.

But I didn't call that kind of method inside the updatePolicyDetails() method. So I need to avoid this popup message.

This the method for popup message.

function awareDisclaimerChanges(vetFee, dentalCover, farewellCover, missingCover) {
    let statement = $("<ul></ul>");
    if (vetFee || dentalCover || farewellCover){
        statement.append("<li>14 day waiting period for Illnesses from today</li>");
    }
    if (vetFee || farewellCover){
        statement.append("<li>48 hour waiting period for Accidents from today</li>");
    }
    if (vetFee){
        statement.append("<li>Waiting period only applies to the increased amount of cover</li>");
    }
    if (missingCover){
        statement.append("<li>14 day exclusion period for Missing Pet cover from today</li>");
    }
    $('#policyDetailsToolTipTitle').text('Information');
    $('#policyDetailTooltipsBody').empty();
    $('#policyDetailTooltipsBody').append(statement);
    $('#policyDetailTooltips').modal('show');
}

I call this method like this.

if (autoRenewalQuote){
    if ($('#farewellYesPet' + id).is(':checked')){
        awareDisclaimerChanges(false,false,true,false);
    }

updatePolicyDetails()

function updatePolicyDetails() {
    var isValidFormFieldsWithoutCovers = $('#policyDetailsForm').valid();
    var isValidCovers = validatePolicyDetailsForm();
    if (isValidFormFieldsWithoutCovers && isValidCovers) {
        $("#loaderModal").modal("show");
        var form = $('#policyDetailsForm');
        var noOfPets = $('#noOfPets').val();
        var properties = [];
