如何在按钮上调用辅助方法在mvc中的视图内单击

Question

我正在使用第三方自定义助手打开报告。我已将其包含在我视图中的另一个辅助方法中，如下所示

var types = ["w", "x", "y", "z"];
var data = [["x", 3], ["y", 4], ["x", 2], ["z", 6], ["z", 3], ["x", 1], ["z", 2]];
var counts = [];
var totals  = [];

_.each(types, function(type, index){
    var count = 0;
    var total = 0;
    _.each(data, function(value, index){
        if(type == value[0]){
            count ++;
            total += value[1];
        }
    });
    counts.push([type, count]);
    totals.push([type, total]);
});
console.log(counts);
console.log(totals);

我需要在按钮或锚点击上调用此辅助方法。我们怎么可能这样做？

我正在尝试这样似乎不起作用的事情

@helper OpenReport(string reportName)
{
   @Html.MvcReportViewer("/FolderName/"+reportName,
   new { Height = 900, Width = 900, style = "border: none" })
}

有什么想法吗？感谢
