used $index and it should work .

<input ng-model="cartdetail[$index]"></input>

revise full code : 

<body  ng-app >
<div ng-init="cartdetail= ['1', '2', '3']">
{{cartdetail}}
<ul><li ng-repeat="num in cartdetail">
       <input ng-model="cartdetail[$index]"></input>
    </li>
</ul>

</div>
</body>

use objects instead of primitives(e.g., number, string, boolean) to bind , so above code will be like 

<body  ng-app >
<div ng-init="cartdetail= [{qty:'1'},{qty: '2'},{qty: '3'}]">
{{cartdetail}}
<ul><li ng-repeat="obj in cartdetail">
       <input ng-model="obj.qty"></input>
    </li>
</ul>
</div>
</body>


hope it work
