Multiselect Issue in ionic multiselect

hello team
i am currently using ionic 1 frame work in which i have integrated multi-select drop down from ionic multi-select js .If i am using single multi-select drop down every thing is working fine

As per my requirement i have to create more than one multi-select drop-down dynamically by using “ng-repeat”,So in this case more than one multi-select drop down has been created successfully . The issue is , if i am selecting value in first drop down ,the same selected values are reflected in other drop downs also ,. As per my understanding this is due to same object assigned in “Items” attribute
Kindly suggest how to handle this situation…

Thank you
