jquery avoid multiple requests preventDefault

I need a way to prevent multiple submits:

$("#myDiv").click(function(e) {

    e.preventDefault();

    console.log('open');



    // submit the form    

    $('#myDiv #myInput').click(function(e){

        e.preventDefault();

        /* ajax call here */

        console.log('clicked');

    });



});

So if when I click #myDiv is sending X times click to the child function.

eg. if you click 3 times #myDiv and then click #myInput will send 3 times the form, and if you press again will send 6.

Any ideas how to fix it?
