Array only being updated on first iteration of a for loop

The following code takes an array of objects structured like so: {html:whatever number:number value}.

function Org(data){
//array of objects
var Data=data;
for(var i=0; i<Data.length; i++){
  var nums=[];
  nums.push(Data[i].number);
console.log(nums);}
}

Nums should have be logged to the console as [1,1] on the second iteration when called with: [{html:null,number:1},{html:null,number:1}] but instead is logged as [1] on both the first and second iterations. Why might this be?
