how to subscribe events like on-select

[rawbin-]

iView: https://www.iviewui.com/components/menu triggered an event named "on-select"

in vue template we use @on-select="selectMenu"

how can we subscribe this kind of event.

all of them worked

    // <Menu theme="light" accordion={this.accordion} style={this.styleObj} {...{on:{"on-select":this.selectMenu}}} >
    // <Menu theme="light" accordion={this.accordion} style={this.styleObj} onOn-select={this.selectMenu} >
    // <Menu theme="light" accordion={this.accordion} style={this.styleObj} on-on-select={this.selectMenu} >

iview的select组件为什么用onChange没有触发呢？
