Pass values of ng-repeat outside it as parameters on button click - angularjs

Question

I have the following code structure where inside a modal-popup, I've populated rows of a table using ng-repeat. Now I want to pass the values of 3 columns of all the rows to the controller but I dont know how exactly I would be able to use the data outside ng-repeat scope and pass to the controller. Here's my code snippet -
<div class="inmodal">
<div class="modal-header" ng-model="modalDetails">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true" ng-click="cancel()">×</button>
<img ng-src={{$root.varImg}} class="m-b-md" alt="profile">
<h4 class="modal-title">{{$root.assetGrpNm}}</h4>
</div>
<div class="modal-body" >
<div class="wrapper wrapper-content animated fadeInRight">
<div class="row">
<div class="col-lg-12">
<div class="table-responsive">
<div ng-repeat="dataag in detail.outerData" >
<table class="table table-striped table-bordered table-hover">
<thead>
<!-- --------- I tried using this piece of code thinking that atleast the values would be inside ng-repeat scope
<tr><button type="button" class="btn btn-primary" data-dismiss="modal" ng-click="save(deviceId,dataDeviceData.measurementData,newDeviceValue,dataDeviceData.lastReadingDateTime)">Save</button></tr>
-->
<tr>
<th>Id</th>
<th>Name</th>
<th>Last Value</th>
<th>Current Value</th>
<th>Date Time</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="dataDevice in dataag.innerData track by $index">
<td>
<span style="font-weight: 800;"><span ng-model="deviceId">{{dataDevice.managedDeviceInfo.id}}</span> - {{dataDevice.managedDeviceInfo.deviceExternalId}}</span>
</td>
<td ng-repeat="dataDeviceData in dataDevice.deviceCoreData">{{dataDevice.managedDeviceInfo.deviceName }} - <span class="text-center">({{ dataDeviceData.quantityUnitSymbol }})</span></td>
<td ng-repeat="dataDeviceData in dataDevice.deviceCoreData">
<input type="number" class="form-control" id="modal_val" ng-model="dataDeviceData.measurementData" required style="width: 100px;"></td>
<td ng-repeat="dataDeviceData in dataDevice.deviceCoreData">
<input type="number" class="form-control" id="modal_val" ng-model="newDeviceValue" required style="width: 100px;"></td>
<td style="position: relative;">
<div id="datetimepicker1-{{$index}}" class="input-append date">
<input data-format="dd/MM/yyyy hh:mm:ss" type="text" ng-model="dataDeviceData.lastReadingDateTime"></input>
<span class="add-on"><i data-time-icon="icon-time" data-date-icon="icon-calendar"></i></span>
</div>
</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal" ng-click="save(deviceId,dataDeviceData.measurementData,newDeviceValue,dataDeviceData.lastReadingDateTime)">Save</button>
<button type="button" class="btn btn-primary" data-dismiss="modal" ng-click="ok()">Cancel</button>
</div>
</div>
Below is an image showing the logic -
