Custom validation in lwc for save and new button?

Question

I want access save and new button in lwc. I have created a custom popup, save and new functionality is not working.

JS code-

 saveAndNewClick(event) {
          // this.redirect = false;
         // this.template.querySelector(".requiredfield").submit(this.inputs);
         // this.resetpage = true;

         saveClick();
          handleReset();
       }
         handleReset() {
           var input = this.template.querySelectorAll(".inputs");
             if (input) {
                input.forEach((input) => {
                    input.reset();
               });
        
      
    }
