howto dynamically change defaults buttons in the grid

[jankrnavek]

Is possible to dynamically change some props on w2ui.grid.buttons much like this?

For example:

w2ui.grid.buttons['reload']['tooltip'] = 'Reload the table and reset all filters'

This statement doesn't take into effect and changes was applied in the grid object correctly.

// change props on grid w2ui 2.0
w2ui.grid.buttons['reload']['tooltip'] = 'Reload the table and reset all filters'

// check changes
console.log('W2ui buttons reload', w2ui.grid.buttons.reload)

W2ui buttons reload 
{type: 'button', id: 'w2ui-reload', icon: 'w2ui-icon-reload', tooltip: 'Reload the table and reset all filters'}
icon:"w2ui-icon-reload"
id:"w2ui-reload"
tooltip:"Reload the table and reset all filters"
type:"button"


// but button "Reload" tooltip has still old value ''Reload data in the list''
