Answer 1

You forgot this class='form-control'

You should change this line

var new_input = "<div><input type='text' id='new_" + new_chq_no + "'pattern='^[0-9]{8}$' required><div class='invalid-feedback'>Enter a correct PhoneNumber!</div></div>";

to this

var new_input = "<div><input type='text' id='new_" + new_chq_no + "'pattern='^[0-9]{8}$' class='form-control' required><div class='invalid-feedback'>Enter a correct PhoneNumber!</div></div>";

hope this could help you:

<div class="form-group row">
    <label for="validationNumber" class="col-2 col-form-label">Contact:</label>
    <div class="col-6">
        <div class="row">
            <div class="col-9 form-group">
                <input id="validationNumber" name="phonenumber" type="text" class="form-control " pattern="\b\d{8}\b" required>
            </div>
            <div class="col-form-label">
                <a class="d-inline m-1" onclick="add()"><label style="cursor: pointer;">Add</label></a>

                <a class="d-inline m-1" onclick="remove()">remove</a>

            </div>
        </div>
        <div class="row form-group">
            <div class="col-9" id="new_chq">
            </div>
        </div>


        <input type="hidden" value="1" id="total_chq">

    </div>
</div>

I changed ur js code a little too:

<script>
    $('.add').on('click', add);
    $('.remove').on('click', remove);

    function add() {
        var new_chq_no = parseInt($('#total_chq').val()) + 1;
        var new_input = "<input class='form-control mb-3' type='text' id='new_" + new_chq_no + "'pattern='^[0-9]{8}$' required><div id='newAlert_" + new_chq_no + "' class='invalid-feedback'>Enter a correct PhoneNumber!</div>";

        $('#new_chq').append(new_input);

        $('#total_chq').val(new_chq_no);
    }

    function remove() {
        var last_chq_no = $('#total_chq').val();

        if (last_chq_no > 1) {
            $('#new_' + last_chq_no).remove();
            $('#newAlert_' + last_chq_no).remove();
            $('#total_chq').val(last_chq_no - 1);
        }
    }
</script>
