[jQuery] newbie question

I have a javascript function like MyFunc(btn), and I would like to
associate a click event to all my button with button1 class in the
page to this function. I tried the following code and is not working
for me:
$("input[@type='button'].button1").each(function()
{
this.click(function(){MyFunc(this);});
});
what's wrong with my code? any help would be greatly appreciated.
