使用多个文本框和下拉列表

I have a drop-down and text box for time calculation of a specific day, in the text box the duration is entered, based on which the timeslot is generated in the drop-down. This works fine for one text box and one drop-down but for multiple text-boxes and drop-downs, it takes the same value assigned to the first text-box. So,How to get the multiple values for each day and what is the mistake. And to display multiple text-boxes and drop-down I have used ng-repeat. Please do help me , if anything is wrong please correct me. Thank you :) I have a drop-down and text box for time calcul
