you can do it as follow:

 $("#addButton").click(function () {

    if(counter>10){
            alert("Only 10 textboxes allow");
            return false;
    }   

    var newTextBoxDiv = $(document.createElement('div'))
         .attr("id", 'TextBoxDiv' + counter);

    newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
          '<input type="text" name="textbox' + counter + 
          '" id="textbox' + counter + '" value="" >');

    newTextBoxDiv.appendTo("#TextBoxesGroup");


    counter++;
     });

     $("#removeButton").click(function () {
    if(counter==1){
          alert("No more textbox to remove");
          return false;
       }   

    counter--;

        $("#TextBoxDiv" + counter).remove();

     });

Here is my JSFiddle with corrected line breaks, or see it below.

$(document).ready(function() {

var MaxInputs       = 2; //maximum extra input boxes allowed
var InputsWrapper   = $("#InputsWrapper"); //Input boxes wrapper ID
var AddButton       = $("#AddMoreFileBox"); //Add button ID

var x = InputsWrapper.length; //initlal text box count
var FieldCount=1; //to keep track of text box added

//on add input button click
$(AddButton).click(function (e) {
        //max input box allowed
        if(x <= MaxInputs) {
            FieldCount++; //text box added ncrement
            //add input box
            $(InputsWrapper).append('<div><input type="text" name="mytext[]" id="field_'+ FieldCount +'"/> <a href="#" class="removeclass">Remove</a></div>');
            x++; //text box increment

            $("#AddMoreFileId").show();

            $('AddMoreFileBox').html("Add field");

            // Delete the "add"-link if there is 3 fields.
            if(x == 3) {
                $("#AddMoreFileId").hide();
                $("#lineBreak").html("<br>");
            }
        }
        return false;
});

$("body").on("click",".removeclass", function(e){ //user click on remove text
        if( x > 1 ) {
                $(this).parent('div').remove(); //remove text box
                x--; //decrement textbox

                $("#AddMoreFileId").show();

                $("#lineBreak").html("");

                // Adds the "add" link again when a field is removed.
                $('AddMoreFileBox').html("Add field");
        }
    return false;
}) 

});

You can also use something like this

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery Add / Remove Table Rows Dynamically</title>
<style type="text/css">
    form{
        margin: 20px 0;
    }
    form input, button{
        padding: 5px;
    }
    table{
        width: 100%;
        margin-bottom: 20px;
        border-collapse: collapse;
    }
    table, th, td{
        border: 1px solid #cdcdcd;
    }
    table th, table td{
        padding: 10px;
        text-align: left;
    }
</style>
<script src="https://code.jquery.com/jquery-1.12.4.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){
        $(".add-row").click(function(){
            var name = $("#name").val();
            var email = $("#email").val();
            var markup = "<tr><td><input type='checkbox' name='record'></td><td>" + name + "</td><td>" + email + "</td></tr>";
            $("table tbody").append(markup);
        });

        // Find and remove selected table rows
        $(".delete-row").click(function(){
            $("table tbody").find('input[name="record"]').each(function(){
                if($(this).is(":checked")){
                    $(this).parents("tr").remove();
                }
            });
        });
    });    
</script>
</head>
<body>
    <form>
        <input type="text" id="name" placeholder="Name">
        <input type="text" id="email" placeholder="Email Address">
        <input type="button" class="add-row" value="Add Row">
    </form>
    <table>
        <thead>
            <tr>
                <th>Select</th>
                <th>Name</th>
                <th>Email</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td><input type="checkbox" name="record"></td>
                <td>Peter Parker</td>
                <td>peterparker@mail.com</td>
            </tr>
        </tbody>
    </table>
    <button type="button" class="delete-row">Delete Row</button>

</html>

You should be able to create and remove input field dynamically by using jquery using this method(https://www.adminspress.com/onex/view/uaomui), Even you can able to generate input fields in bulk and export to string.

Jquery Code

$(document).ready(function() {
    var max_fields      = 10; //maximum input boxes allowed
    var wrapper         = $(".input_fields_wrap"); //Fields wrapper
    var add_button      = $(".add_field_button"); //Add button ID

    var x = 1; //initlal text box count
    $(add_button).click(function(e){ //on add input button click
        e.preventDefault();
        if(x < max_fields){ //max input box allowed
            x++; //text box increment
            $(wrapper).append('<div><input type="text" name="mytext[]"/><a href="#" class="remove_field">Remove</a></div>'); //add input box
        }
    });

    $(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $(this).parent('div').remove(); x--;
    })
});

HTML CODE

<div class="input_fields_wrap">
    <button class="add_field_button">Add More Fields</button>
    <div><input type="text" name="mytext[]"></div>
</div>

why not remove the .after() in the line

newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +

newTextBoxDiv.html('<label>Textbox #'+ counter + ' : </label>' +
