Angular json array data not inserting in mysql db using node js

Question

I am creating a Json object. Inside that I am creating an array, the array will push some fields dynamically when user clicks add buttons, I want to store the dynamic fields values in scope variable called table and passing that to submit() function, so when the user clicks the save button it calls the submit() function, where it send that field values to node using $http. The values which is sent to node js server is not inserting in tables

HTML

<form ng-controller="NewTableCtrl" ng-app="myApp" name="frm" class="form-inline" ng-submit="submitTable()">
      <input type="string" name="cat_name" class="form-control" ng-model="table.cat_name" placeholder="Enter Category Name" ng-pattern="/^[a-zA-Z]*$/" required>
