切换按钮在Gridview不工作？

Question

我创建了一个切换按钮，通过4个状态切换单个按钮！

切换按钮位于GridView中，而GridView又嵌套在FormView中。该按钮在HTML页面中运行良好，并在选择4个图像中的每一个图像时根据需要将该值提交到文本框中。但是在GridView中它不会工作！任何人都可以协助或有任何我应该知道的已知问题吗？

<script type="text/javascript"> 
    $(document).ready(function() { 
    $(".imageButton").ready(function() { 
      $("img").click(function() { 
       if ($(this).attr("src") == "../../../images/tick_50.png") { 
        $(this).attr("src", '../../../images/excl_mark_50.png'); //orange image 
        $(this).parent().siblings("input").attr("value", '2'); 
       } else if ($(this).attr("src") == "../../../images/excl_mark_50.png") { 
        $(this).attr("src", '../../../images/cross_50.png'); //red image 
        $(this).parent().siblings("input").attr("value", '3'); 
       } else if ($(this).attr("src") == "../../../images/cross_50.png") {

$(document).ready(function() { 
      $('.imageButton').find('img').on('click', function() { 
       if ($(this).attr('src') == '../../../images/tick_50.png') { 
        $(this).attr('src', '../../../images/excl_mark_50.png'); //orange image 
        $(this).parents('.imageButton').find('input').val('2');
