i am doing something like this
    

     
//dom
     
    <div id='parent'>
     
    </div>
     
    //js
     
    var _doSomeThing=function()
     
    {
     
    //some codes
     
    }
     
    $(function(){
     
//appending div and binding methods to span
     
    $('#parent).append('<span>1</span>');
     
    $('#parent).append('<span>2</span>');
     
    $('#parent span').bind('click',_doSomeThing);
     
    });
     
function _clearDiv()
     
{
     
//clear div
     
$('#parent).html('');
     
}
     
//sometime in future, call clear div
     
_clearDiv();
    

now my question is, binding events to dom and later just removing the 
elements from dom leads to memory leakage.

I read some where that doing this will lead to memory loss. As i just cleared the 
div without unbinding the events.
my question is if i use $('#parent').empty()- to clear the div is this will
avoid memory leakage
if yes how to solve this problem.
