I figured it out. Apparently it reinitializes the variables in the apex class everytime I do a rerender because they are being set in their respective {get; set;} so I just moved the initializations to the constructor and now it is rendering just fine

Hi,

Can you try changing the id to modelsId and if this also doesn't work then try reRendering the whole form using reRender="form".

Let me know if need more help on this.

Thanks,
Abhishek Bansal.
