Problem with element and Maximize

I'm not sure what I am doing wrong.  I am trying to get the nearest
integer maximim for the mentioned equation.  I could round the X
value, but I would like to operate Mathematica correctly.

(*generate the equation*)
data = {{0, 0}, {10, 10}, {20, 0}, {30, 10}};
eq = Fit[data, {1, x, x^2, x^3}, x] 
Plot[eq, {x, 0, 30}]

Maximize[{eq, x \[Element] Integers}, x]  (*wrong!*)

Maximize[{eq}, x]      (*correct, but not integer, of course*)

Best Regards,
