[Vuejs]-Materialize modal popup auto initialize not working in vue js

I have called the same function from VueJs updated event

updated() 
{ 
            this.testingmodel(); 
        },

** But you have to avoid the errors by using try catch on calling function

testingmodel:function(){ 
             $('#firstlogintour').modal('open'); 
        }

Vue Updated Scenario:

This function will call up to when the function or method loads without failure or any Error.
