Filter in angularjs

This is my html code.

<body ng-app="app" key-trap>
<div ng-controller="Controller">
<input type="text" class="myInput form-control" name="txtStorename" id="txtStorename" placeholder="Search for Store.." title="Type in a Store" data-error-message="Please enter StoreName" ng-model="obj.sname">
<ul ng-if="obj.sname && obj.showList" id="myUL" ng-repeat="StoreList in Store| filter:obj.sname">
<li class="record" ng-class="($index == focusIndex)?'record-highlight':''" ng-cloak ng-click="SelectedValue(StoreList.StoreName)">{{StoreList.StoreName}}li>
ul>
<div ng-show="(Store|filter:obj.sname).length==0" style="color:red;font-weight:bold" ng-cloak>No Result Founddiv>
div>

And this is my Angular JS code.

Everything in the code is fine. I'm getting data from database in angularjs using $scope.GetallItem Function.

Problem is when I filter using the keyboard it filters well. As I use the enter key from keyboard to select it returns me as [Object object] instead of data value. I want is that on pressing enter key it gets me the value instead of [Object object]
