Problems with custom validation of iview forms

there is a reference example in the documentation in iview

<FormItem    v-for="(item, index) in formDynamic.items"
             v-if="item.status"
             :key="index"
             :label=""Item " + item.index"
             :prop=""items." + index + ".value""
             :rules="{required: true, message: "Item " + item.index +" can not be empty", trigger: "blur"}">
        </FormItem>

now implement custom validation in rules

<FormItem v-if="actionLabel!==""&&showActionValType===1"
                          :label="actionLabelText"
                          prop="actionValDIM"
                          :rules="{required: true,validator:"validateInt" , trigger: "blur"}">
                    <Slider v-model="programForm.actionValDIM" :tip-format="format" style="width: 400px"></Slider>
                </FormItem>

how to pass the function validateInt in

it"s like a document in data. It"s written in OK, but I think there"s a problem with uploading it in": rules= "{required: true,validator:"validateInt", trigger: "blur"}"

.
ruleCustom: {
                    passwd: [
                        { validator: validatePass, trigger: "blur" }
                    ],
                    passwdCheck: [
                        { validator: validatePassCheck, trigger: "blur" }
                    ],
                    age: [
                        { validator: validateAge, trigger: "blur" }
                    ]
                }

//  validateInt  data 
const validateInt = ()
data () {
    return {
        validateInt: validateInt
    }
}
// 
:rules="{required: true,validator:'validateInt' , trigger: 'blur'}"
// 
:rules="{required: true,validator: validateInt, trigger: 'blur'}" 
//  required validateInt 

: rules= "{required: true,validator:'validateInt', trigger: 'blur'}"

Change

to
: rules= "intRule"
and then click

data () {
    return {
        intRule: {required: true,validator:validateInt , trigger: 'blur'}
    }
}
