This paper has some errors in analysis, plots and tables. On the other hand, we have submitted a paper identified by arXiv:1910.03514, which could be considered as an update for this paper, arXiv:1609.03816. But the new one has lots of changes in tables, plots, text, order of authors and even category

Three general models of dynamical interacting dark energy (D-class) are investigated in the context of Brans-Dicke cosmology. All cosmological quantities such as equation of state parameters, deceleration parameters, Hubble function, and the density ratio are calculated as a function of redshift parameter. The most important part of this paper is fitting of models to the observational data (SNIa+BAOA+Omh2). We obtain a table of best fit value of parameters and report χtot2/dof and Akaike Information Criterion (AIC) for each model. By these diagnostic tools, we find that some models have no chance against ΛCDM and some (e.g. BD-DC2 and BD-DA^*) render the best fit quality. Specially, the value of AIC analysis and figures show that the interacting BD-DC2 model fit perfectly with overall data and reveals a strong evidence in favor of this model, against ΛCDM.
