I am working with the Grid control in AngularJS and I am trying to figure out if there is a way to update all the column data with data input taken from the header template. I am using template on a column which has a textbox and header template having a textbox. As per the requirement, when the user gives an input on the header textbox all the textboxes in the column should be updated with the user input on the header. Here is the attached plunkr where the discount column has a textbox in the header. The column data is all textboxes. When the user input a value on the header, all the column textboxes must be updated with the value.
