How to generate ng-model dynamically in ng-repeat?

Question

JavaScript

Is it possible to somehow form ng-model dynamically? So that in ng-repeat an individual ng-model is formed for each element.
For example: ng-model="document1 .. 2 .. 3 etc." by setting something like documents+id.

<div class="col-xs-12" 
      ng-repeat="doc in docsAttr">
      <div class="form-group material form-md-line-input form-md-floating-label">
        <input type="text" class="form-control" 
        id="{{ doc.id}}" 
        ui-mask="9999" 
        data-position="{{doc.position}}" 
        ng-model="doc+$index" />
        <label for="{{ doc.alias }}">{{ doc.name }}</label>
        <span class="help-block"> Например: {{ doc.example }} </span>
      </div>
    </div>

UserDocumentsAttr.getAttr().then(function(res){
      $scope.docsAttr = res.data;     
    });
for (var i = 0; i <= 4; i++) {
        docs.push({
          id: $scope.docsAttr[i].id, 
          name: $scope.doc+i    // Присвоить значение из ng-model
        });
      };
