How dynamically assigning values ​to a property of an object?

I am coding a node module with

for node.js, in this module I have a function called which allows to execute a stored procedure by just sending a db connection, the name of the stored procedure, the parameters, I added a callback function to return my recordset, in the parameters I send an array with the names of the parameters, the values and the SQL Server data types, this is the Array:

[{name:'num',type:'Int',value:2},

{name:'num1',type:'Int',value:1}]

This is my function:

exports.sp_recordset = function(conex, storedProcedure, parameters, cb) {



var connection = new mssql.Connection(conex, function(err) {

  if(err){

    console.log(err);

  }



  var request = new mssql.Request(connection);



  for(index=0;index<parameters.length;++index)

  {

    request.input(parameters.name, mssql.Int, parameters.value);

  }



  request.execute(storedProcedure, function(err, recordsets, returnValue) {

    if(err){

      console.log(err);

    }

      cb(recordsets);

  });



});  



};

In this line line is my problem:

request.input(parameters.name, mssql.Int, parameters.value);

As I said, the need is a dynamic function, the second parameter (SQL Server data type also has to by dynamic), which is the best way to assign the data type to ? I have tried this but it doesn't works:

request.input(parameters.name, mssql.(parameters.type), parameters.value);
