bind event only once

Question

I have the following code:

function someMethod()
{
  $(obj).click(function {});
}

someMethod is called twice and thus click event is binded

Answer 1

var bound = false;

function someMethod()
{
    if(!bound)
    {
       $(obj).click(function {});
       bound = true;
    }
}

but I would probably look into why it;s being called twice before making some kind of workaround.
