Calling a bean method from an onClick event

[zemanel]

Hello,

I have a dataTable with an HtmlInputText on each cell, i want to add an onClick event for each inputText, so when i click on it, the values changes to a value stored on backbean, and when i clickout the old value comes again.
The inputText have an setOnClick(String) method, but how can i get the bean value through a javascript function? i wanted to do something like:

dataTable.setVar("myItem");
 dataTableMatriz.setValue(matriz); // ArrayList of ArrayLists

 ValueBinding myItem = FacesContext.getCurrentInstance().getApplication().createValueBinding("#{myItem.get(" + i + ").valueX}");
 input.setValueBinding("value", myItem);

 inputText.setOnClick("this.value = " + *set to a valueY just while selected* ";");
 input.setOnblur("this.value = " + *set again to valueX* ";");

Any idea how to get this?
Thanks
