I have a function called on the popup dialog in vue as:

methods : {
 open() {
   do the stuff, 
  }
}

now in my above code, i have to use setTimeout to make sure the items are loaded inside the popup and so i can use some setAttribute to add some items to existing code

instead of using setTimeout, i wanted to use use the mounted to use this.$.nexttick() and then load the method in this, how can do this so it works the same way without setTimeout
