Load iframe completly.

Load iframe completly.

Hi.

I use this code for load an iframe:
$("#button_body").click(function () 
{
    $("#KeyShotVR").html("<iframe id='teste1' name='nomeIframe' src='http:/meusite/teste/body.html' width=' 1023' height='575' frameborder='0'></iframe>")
})

This function corectly.

But I need to know when this iframe is completely loaded. 

I try this:
$("#teste1").load( function (){
alert("ok");
});

But anything happens...

Any help?

Thanks
