Clear css of a particular row of a dynamically created table.

Actually, I've a code where a table will created dynamically and the cells can be selected. The background color of the (selected) cells will be changed and it can be cleared with a button. But the thing is, it'll clear the entire table's (selected cells) background color. But what I want is to clear background color of a particular row. Here I could select and display states of a row. But can't clear with this. Here is the code: plnkr.co



P.S.: Actually I need a multiple time slot selecting plugin same like the above example. If have something similar to the above, please don't hesitate to suggest.
