how to get command argument of link button in radiobtnlist?

Question

i have got 4 linkbutton controls with command arguments....when the linkbutton is clicked it populates the datalist based on the command argument...

and i have a radio button list control that filters  the data  according to price that is populated in the datalist......

on page load,the datalist is populated with all the items....when i use rbtnlistcontrol on page load,it works as expected, but when i click any link button and then price radiobutton control,it doesn't filter the result/data.....

 

here's my html,
