Using vue.js/Vanilla js, I want to put the data being pulled via the checkbox into an "inquiryObj" object and send it to a parent component in an array of "inquiry" objects by emit, but when I uncheck the checkbox it creates an object equals instead of removing from the array of objects.

how am i doing:

    async inquiryPage(estate)
    {
      if (this.inquiry.includes(estate.id))
      {        
        this.inquiry = this.inquiry.filter((item) => item !== estate.id);
        this.inquiry = this.inquiry.filter((item) => item !== 'ikkodate');
        this.inquiry = this.inquiry.filter((item) => item !== estate.estateName);
        this.inquiry = this.inquiry.filter((item) => item !== estate.estatePrice);
      } 
        else
        {          
          this.inquiryObj.push(estate.id);
          this.inquiryObj.push('ikkodate');
          this.inquiryObj.push(estate.estateName);
          this.inquiryObj.push(estate.estatePrice);

          let obj = Object.assign({}, this.inquiryObj);
          this.inquiry.push(obj)
        }    
          await this.$emit("inquiry", this.inquiry)               
    }

the project is running on vue 2.6.11
