Use addEventListener and/or attachEvent[^] to bind your function to the click event.

Hi,
I have added the the following line
newDeleteButton.addEventListener('click',alert("ok"),false);

But alert in is invoking when button is added. Need to alert when I click on the added button.

If you do that, you are calling alert("ok") at the time that you add the button. You need to wrap the code you want to call when the button is clicked inside a function:


function clickedFunction()
{
  alert("ok");
}

...

newDeleteButton.addEventListener('click',clickedFunction,false);
