How to use checkbox to run different Cesium Model?

My goal is runing the cesium models with checkbox. Like, there are 3D Models Coloring, GeoJSON and TopoJSON, Polyline...etc. and there are some checkbox to relate the models. If I check 3D models coloring checkbox, this model shows on the globe, if I uncheck, there is no more model. If I check two checkbox, It will show two models on the globe. Some thing like that.

Thanks!
