ng-grid click edit to open pop-up - angularjs

Question

I've a ng-grid which has Edit, and Delete buttons at the bottom of the grid.
On clicking the Edit button, I want it to open a Modal pop-up with info. from selected rows shown in the modal.
This is my HTML.
<div class="gridStyle" ng-grid="gridOptions"><!--ng-grid-->
</div>
<button ng-click="??" ng- disabled="!singleSelection()">Edit</button>
<button ng-click="??" ng-disabled="disabled">Delete</button>
And my JS is as follows:
$scope.gridOptions = {
data: 'scheduleData.scheduleList',
columnDefs: [
{ field: 'id', displayName: 'ID', visible: false },
{ field: 'disabled', displayName: 'Enabled', cellFilter: 'checkmark' }
{ field: 'dpName', displayName: 'Description' },
{ field: 'dpType', displayName: 'Type' },
{ field: 'dpProtection', displayName: 'Protection' },
{ field: 'doProtectionParam', displayName: 'DP Protection Paramters', visible: false },
{ field: 'startDate', displayName: 'Start Date', visible: false, cellFilter: 'date:\'M/d/yy h:mm a\'' },
{ field: 'endDate', displayName: 'End Date', visible: false, cellFilter: 'date:\'M/d/yy h:mm a\'' },
{ field: 'recurrenceType', displayName: 'Recurrence' },
{ field: 'everyNth', displayName: 'Estimated Duration', visible: false },
enableCellSelection: false,
enableSorting: true,
enableColumnResize: true,
enableColumnReordering: true,
showColumnMenu: true,
showFilter: true,
showFooter: true,
enableRowselection: true,
multiSelect: true,
selectedItems: $scope.selections
};
Any help will be greatly appreciated.
Thanks

I got this to working making the foll. change to HTML
<button ng-click="openModal(selections[0])" ng- disabled="disableButtons(selections)">Edit</button>
And in my JS,
$scope.openModal = (selections) => {
var modalInstance = $modal.open({
templateUrl: 'link to URL',
controller:RelatedController,
resolve: {
schedule: function () {
return selections.id == null ? selections : selections.clone();
}
}
});
}
