单击按钮调用函数

Question

I have written the script as follows:

<script type="text/javascript">
    $(document).ready(function(){
        $("#Click").click(function(){
            var data1 = new Object();
            data1.name = $('#databases').val();
            $.ajax({
          url : "form_submit",
          type : 'POST',
          data : data1,
          dataType : "text",              
          success : function(data){
            data = JSON.parse(data);
            var output="<table id=tableStyle>";
            output+="<tr>" + "<th>" + "REPORTSUITE_ID" + "</th>" + "<th>" + "REPORTSUITE_NAME" + "</th>" + "<th>" + "STAGING_DATABASE" + "</th>" + "<th>" + "DWH_DATABASE" + "</th>" + "</tr>";
            for (var i in data)
            {
                output+="<tr>" + "<td>" + data[i].REPORTSUITE_ID + "</td>" + "<td>" + "<button type = \"buttion\" id =\"tableList\">" + data[i].REPORTSUITE_NAME + "</button>" + "</td>" + "<td>" + data[i].STAGING_DATABASE + "</td>" + "<td>" + data[i].DWH_DATABASE + "</td>" + "</tr>";
            }
            output += "</table>";
            document.getElementById("placeholder").innerHTML=output;
          }
          });
        });
        });
    $("#tableList").click(function(){
            alert("this is data");
            });
</script>

On the clicking of button with id = tableList, i want the alert with message "this is data" to be displayed but it does not display anything. I also tried with pasting the code related to click of button with id tableList between different tags, still it did not work. Please help

Hi used event delegation for the above question as pointed out as follows:

<script>
    $(document).on("ready",function(){
        $("#placeholder").on("click","button",function(event){
            alert("id is " + this.id + "for database " + $('#databases').val())
        })
    });
</script>

The value is being passed correctly. Thanks for the pointer.
