Recursive call inside jquery plugin

Why is the function working only once in the below code ?

(function ( $ ) {

$.fn.test = function() {

   setInterval(hi.call(this), 1000);

   function hi(){
    console.log(this);
   }
};

}( jQuery ));


$('div').test();

call() calls the function with a this-value and optional arguments, it would be the same as

setInterval(hi(), 1000);

and as that function doesn't return anything, it's the same as

var x = hi(); // undefined

setInterval(x, 1000);
       //   ^ still undefined

What you wanted was to create a new function with a given this-value using bind()

setInterval(hi.bind(this), 1000);

A little more jQuery'ish using $.proxy

setInterval( $.proxy(hi, this), 1000);
