Issue with JQuery window resize function calls - event-handling

Question

I have a resize method in my js file :
$(window).resize(function(){
my_function();
});
In it i have loads of other functions which need to be called when the window is resized (for the responsive part of a website) ,i have not included all these functions as the problem i keep facing is the same in the one i am about to post.
It can't be simpler :
function my_function() {
console.log('1');
$('body').click(function(){
console.log('2');
});
}
my_function();
//when the function is called the console logs 1,when you click on the body ,it logs 2.
Now the problem, when I resize the window (for example : from full window to half in 2s),the resize() fires a couple of times (for example : 10 [every time it's different]).I know this because in the console the number 1 is called/logged 10 times as the window is being resized.Now,after i finished resizing the window, when i click on the body, the console logs the number 2 the same amount of times (10).
Why ? And how can i make it fire the click.function only once ?

UPDATE 1 : in addition,every subsequent click on the body logs 2 another 10 times (so if i click 5 times,the console will log the number 2 50 times.
