nisam ni "e" od eksperta za js, ali, moze li ovo pomoci (na brzinu sam nesto popricao s googletom):

To pass a function as a string, be sure to suffix the function name with parentheses.

window.setInterval("someFunction()", 5000);

When passing a function pointer, do not include the parentheses.

window.setInterval(someFunction, 5000);
