禁用textarea复选框：使用bootstrap-switch检查

I have an MVC app where I have a class of bools. There is a textarea next to each switch to enter comments if the item is indicated as rejected (returns false). I need to have the textarea disabled if the the swith is set to Accepted (returns true). I have searched ad nauseum and can't find a suitable solution. I know that there is an on-change event handler built in to bootstrap-switch but I am struggling to avoid an indivisual line for each bool field rather than using (this).I have an MVC app where I have a class of bools
