I don't know if the title explain this situation well. Below is a code i wrote to create div elements when the button is pressed. Then By clicking on any of the created divs, we can change the div background by choosing a color from the drop down box. However if i click on another div and tried to change the color by selecting another color from the drop down, the previously clicked divs also gets affected by the new color. Why is this happening. I only want the selected div to change color, without affecting the previously clicked divs. I read allot of threads on this site, some of which talks about unbinding clicks, but I'm unable to solve the problem. Thanks for the help.

</style>

    <option value="1">red</option>

<script type="text/javascript">
var dividcount = 1;
$("button").click(run);
function run(){
 var myDiv = $('<div id=lar'+dividcount+' class=aaa></div>');
 $(myDiv).clone().appendTo('#ptest');
 $(dividcount++);
 $("div").bind('click',(function() {
  var box = $("div").index(this);
  var idd = (this.id);
  $("#"+idd).text("div #"+idd);
  $("select").change(function(){
   var str= $("select option:selected").text();
   $("#"+idd).css("background-color",str);
  });
 }));
};
