Angular JS: ng-repeat with dynamic ng-model

Question

I have this working piece of code that is repeated multiple times, hence would be great for a ng-repeat loop. For example, two instances of my code are the following.

    <div>
        <input type="text" ng-model="searchParamaters.userName" placeholder="User Name"/>
        <i class="fa fa-times" ng-click="resetSearchField(filterParamDisplay[0].param)" ng-show="showParam(filterParamDisplay[0].param)"></i>
    </div>
    <div>
        <input type="text" ng-model="searchParamaters.userEmail" placeholder="User Email"/>
        <i class="fa fa-times" ng-click="resetSearchField(filterParamDisplay[1].param)" ng-show="showParam(filterParamDisplay[1].param)"></i>
    </div>

This is the filterParamDisplay array in Javascript:

    $scope.filterParamDisplay = [
        {param: 'userName', displayName: 'User Name'},
        {param: 'userEmail', displayName: 'User Email'}
    ];

I have been trying to do that into a ng-repeat loop, but without success so far. This is what I have coded atm.

    <div ng-repeat="param in filterParamDisplay">
        <input type="text" ng-model="searchParams[{{param}}]" placeholder="{{param.displayName}}"/>
        <i class="fa fa-times" ng-click="resetSearchField(filterParamDisplay[$index].param)" ng-show="showParam(filterParamDisplay[$index].param)"></i>
    </div>

The problems are into the ng-model variable above, and into the $index in the ng-click and ng-show. Not sure if this can be done at all, any help is much appreciated, thanks!

UPDATE: Thanks for all the answers, using

     <div ng-repeat="p in filterParamDisplay">
...
   ng-model="searchParams[p]" 

Works great!

Still struggling on the showParam and resetSearchField functions which do not work properly yet using $index. Here is my code.

    $scope.searchParams = $state.current.data.defaultSearchParams;

    $scope.resetSearchField = function (searchParam) {
        $scope.searchParams[searchParam] = '';
    };

    $scope.showParam = function (param) {
        return angular.isDefined($scope.searchParams[param]);
    };

Answer 1

As you bind your ng-models to searchParameters.userName and searchParameters.userMail at first example, you must use searchParameters[param.param] for ng-model in ng-repeat. Also like others said, you don't need to use $index, you got your object as param in ng-repeat scope.

<div ng-repeat="param in filterParamDisplay">
    <input type="text" ng-model="searchParameters[param.param]" placeholder="{{param.displayName}}"/>
    <i class="fa fa-times" ng-click="resetSearchField(param.param)" ng-show="showParam(param.param)"></i>
</div>

Here is working FIDDLE

<div ng-app="dynamicAPP">
    <div ng-controller="dynamicController">
        <div ng-repeat="param in filterParamDisplay">
            <input type="text" ng-model="searchParams[param.param]" placeholder="{{param.displayName}}" /> <i class="fa fa-times" ng-click="resetSearchField(filterParamDisplay[$index].param)" ng-show="showParam(filterParamDisplay[$index].param)"></i>
        </div>{{searchParams}}</div>
</div>

Jsfiddler link this one for get a single object like 'username' or 'email'

you want single value in ng-show and ng-click use above one. or other wise use belowed one.

<div ng-app="dynamicAPP">
    <div ng-controller="dynamicController">
        <div ng-repeat="param in filterParamDisplay">
            <input type="text" ng-model="searchParams[param.param]" placeholder="{{param.displayName}}" /> <i class="fa fa-times" ng-click="resetSearchField(.param)" ng-show="showParam(param)"></i>
        </div>{{searchParams}}</div>
</div>

Jsfiddler link this one is get whole object based on the control

this will passes the whole set of object list.
