我正在使用select2库，我有以下代码：

$("#brand_id").on('change', function(){
    let brand_id = $("#brand_id").val()
    if(brand_id){
        console.log('changed')
        toggleDisabled($("#bike_situation_id"), false)
        $("#bike_situation_id").val("1").change()
    } else {
        toggleDisabled($("#bike_situation_id"), true)
    }
})

我遇到的问题是 $("#bike_situation_id").val("1").change() . 因为如果我这样做了 console.log($("#bike_situation_)id").val()) 回报是 1 ，但选择框不会更新。
我的html元素：

<div class="container">
                        <label>Marca: <img src="{% static './assets/info.svg' %}" id="info-brand" width="15px"
                                height="15px" /></label>

                        <select name="brand" id="brand_id">
                            <option value="">---------</option>
                        </select>
                        <div id="modal-brand" class="modal">
