We obtain constrains on different relevant parameters of this model from the observational data. We consider a homogeneous scalar field $\\phi(t)$ driven by a $k-$essence Lagrangian of the from $L = V(\\phi)F(X)$ with constant potential $V(\\phi) = V$, to describe the dynamics of dark energy in this model.
