Bind data in select multiple with jquery

Question

I am using select multiple control using selectsize.js here is my control

<div class="default selectize-control multi">
                            <select multiple id="select-email" class="selectize-input items has-options has-items full">
                                @*<option value="0">Zero</option>
                                <option value="1">One</option>
                            </select>
                        </div>

I am trying to bind this control through ajax here is my Ajax code

var selectemailemail = $("#select-email");
        selectemailemail.empty().append('<option selected="selected" value="0" disabled = "disabled">Loading.....</option>');
        $.ajax({
            type: "GET",
            url: "/api/Customer/GetCustomerList",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data)
            {
                console.log('response', data);

                for(var i=0;i<data.length;i++)
                {
                    console.log('data[i].email' + data[i].Email);
                    $("<option value=" + data[i].TokenId + ">" + data[i].Email + ")</option>").appendTo(selectemailemail);


                }
                selectemailemail.multipleSelect('refresh');
            },
            failure: function (response)
            {
                alert(response.responseText);
            },
            error: function (response) {
                alert(response.responseText);
            }
        });
    };

while running ajax codei am getting data in an array here is the data in an array

                $("<option value=" + data[i].TokenId + ">" + data[i].Email + ")</option>").appendTo(selectemailemail);
