AngularJS Table Column Search...smarter ideas? - angularjs

Question

I have to use AngularJS to build a dashboard and one of the components is a table.
Since I did not find relevant dependencies/libraries for angularjs (like tabulator or datatables), I am doing it myself.
Instead of using the native angular filter, I built a custom method, but I am not sure if I am following a good approach.
The main idea is that when I pull the data object (array of objects) via Ajax, I create both an "original" and a "current" data object,s and at the beginning, they are exactly the same of course.
Then I created an input field above every column heading and I linked the search function to the blur and keyup events (enter key).
When the search function is triggered, I start making changes to the "current" object. This way I can filter by multiple columns incrementally. I filter the data object using an awesome library called AlaSQL.
I also linked to a button the "reset" method, which simply makes the "current" object equal to the "original" object, and cleans up the input fields.
The point is, am I missing any best practices? Are there better ways to do so with AngularJS?
Any suggestions?
Thanks a lot.
