Asp.net mvc 引导模式数据解除按钮正在发布表单

我在bootsrap模式中有一个表单。当我单击submit时，它发布数据并隐藏模式。伟大的但是，如果单击具有“数据解除”属性的“取消”按钮，它也会提交表单。我尝试了explicit type=button，但它仍然提交表单。我想取消按钮只是关闭模式，而不是做回发。有什么建议吗

<div Class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

缺少模式页脚按钮模式应为-

<Button Class="btn-grey" type="button" data-dismiss="modal">Cancel</button>
