angularjs select ng-options click not responding

html writes

<div>
<select ng-model="selectedGraph.selected.graphId" class="" id="qtSelect" ng-change="selectGraph()"
ng-options="graph.graphId as graph.graphName for graph in graphList"></select>
</div>

 After the page is rendered, no matter how you click, there is no response, neither on the PC side nor on the mobile phone side. After Baidu, it was necessary to add an attribute ( data-tap-disabled="true" ).

<div data-tap-disabled="true">
        	<select ng-model="selectedGraph.selected.graphId" class="" id="qtSelect" ng-change="selectGraph()"
                    ng-options="graph.graphId as graph.graphName for graph in graphList"></select>
        </div>
