我测试微信小程序，运行 ok，可以参考下面 demo 运行

https://gitcode.net/xiurensha5731/uni-app-questions/-/blob/main/src/pages/index/index.vue

index page

<template>
  <div>
   <div>你输入了：{{ str }}</div>
    <myInput v-model:count="str"></myInput>
  </div>
</template>
<script lang="ts" setup>
import { ref } from "vue";
import myInput from "../../components/my-input.vue";
const str = ref("2");
</script>

对应组件 my-input

<template>
  <div>
    <input
      type="text"
      v-model="count"
      style="height: 20px; border: 1px solid black"
    />
  </div>
</template>
<script lang="ts" setup>
const count = defineModel<string>("count", { default: "" });
</script>

<style></style>
