Blinking Text If checkbox is checked to true

I am trying to create when user check checkbox to yes(true) in Index Page Emergency column needs to flash text something like Emergency But unfortunately I try couple of methods but unsuccessfully. Here is so far what I did

@if (Model.Count() > 0)
    {
        <table class="table table-bordered table-striped" style="width:100%">
            <thead>
                <tr>
                    <th>
                        Doctor Full Name - CODE
                    </th>
                    <th>
                        Patient Full Name
                    </th>
                    <th>
                        Date and Time
                    </th>
                    <th>
                        Emergency
                    </th>
                    <th></th>
                </tr>
            </thead>
            <tbody>
                @foreach (var obj in Model)
                {
                    <tr>
                        <td width="25%">@obj.Doctor.Firstname @obj.Doctor.Lastname @obj.Doctor.Code</td>
                        <td width="25%">@obj.Patient.FirstName @obj.Patient.LastName</td>
                        <td width="25%">@obj.DateAndTime</td>
                        @if(obj.Emergency == true)
                        {
                            <span class="blink_me">Emergency</span>
                        }

                        <td class="text-center">
                            <div class="w-75 btn-group" role="group">
                                <a asp-route-Id="@obj.Id" asp-action="Upsert" class="btn btn-primary mx-2">
                                    <i class="fas fa-edit"></i>
                                </a>
                                <a asp-route-Id="@obj.Id" asp-action="Delete" class="btn btn-danger mx-2">
                                    <i class="far fa-trash-alt"></i>
                                </a>
                            </div>
                        </td>
                    </tr>
                }
            </tbody>
        </table>
    }
    else
    {
        <p> No Admission Patient exists.</p>
    }

@section Scripts{
    <script>
        (function blink() {
            $('.blink_me').fadeOut(500).fadeIn(500, blink);
        })();
    </script>
}
