question about nest

Dear Wizards I have a function with two variables f[x_,a_]:=a*x*(1-x) And I need the n-compose function Nest[f,x,n] But Mathematica look for a function f[x] and not f[x,a] Is this possible to use Nest with this two variable function? For example, I need f[x,a], f[f[x,a],a], f[f[f[x,a],a],a] . Later I will put many values for "a" . Regards Orlando Peres
