[我想在VUE js中单击按钮时显示模态框

Question

我已经使用bootstrap和VUE js创建了代码。当我单击按钮时，弹出窗口不显示。我使用了VUE js组件。我希望我的输出看起来像https://prnt.sc/pkhrff，但是现在我单击按钮时什么也没发生。我的代码在这里查看！

<div class="register-wrap"  id="register-wrap">
    <div class="container">
        <h2>Online registration for Vue Training</h2>
        <div class="line"></div>
        <div class="row">
            <div class="col-md-12 col-sm-12 col-12">
                <div class="registerbtn">
                    <h3>Register Now Today!</h3>
                    <modalregister v-if="showModal" @close= "showModal = false">
                        <p>Enter your text here</p>
                    </modalregister>
                    <input type="submit" @click = "showModal = true" class="form-control" value="Register Now">
                </div>
            </div>
        </div>
    </div>
</div>

VUE js：

Vue.component('modalregister',

    template:`
            <!-- Modal -->
            <div class="modal fade">
                <div class="modal-dialog">
                    <!-- Modal content-->
                    <div class="modal-content">
                        <div class="modal-header">
                            <slot></slot>
                        </div>
                        <button class="close" type="button" data-dismiss="modal" @click="$emit('close')"></button>
                    </div>

                </div>
            </div>

    `
);

new Vue(

    el:'#register-wrap',

    data: 

        showModal: false
    

);
