setValue() on datefield doesn't work as expected

[sencha-dev2]

Hi,

I have to make a grid which refreshes data and column headers by buttons and date-picking.

For the date-picking part, function works fine, but for the button one, the headers don't refresh and the value in the field stays the same. Can somebody help me ? Here's the function on the button for the previous week :

onBtnSMoinsClick: function(button, e, options) {
    var date = Ext.ComponentQuery.query('datefield[itemId="dateS"]')[0];
    console.log(date.getValue());
    date.setValue(new Date(date.value.getFullYear(), date.value.getMonth(), (parseInt(date.value.getDate(), 10) - 7)));
    console.log(date.getValue());
    date.fireEvent('select', date, date.getValue());
}

And here is the select event fired :

onDatefieldSelect: function(field, value, options) {
    var headerL = field.up().up().down('gridcolumn[dataIndex="plateauxLundi"]'),
    headerM = field.up().up().down('gridcolumn[dataIndex="plateauxMardi"]'),
    headerMe = field.up().up().down('gridcolumn[dataIndex="plateauxMercredi"]'),
    headerJ = field.up().up().down('gridcolumn[dataIndex="plateauxJeudi"]'),
    headerV = field.up().up().down('gridcolumn[dataIndex="plateauxVendredi"]'),
    headerS = field.up().up().down('gridcolumn[dataIndex="plateauxSamedi"]'),
    headerD = field.up().up().down('gridcolumn[dataIndex="plateauxDimanche"]'),
    head = [headerL, headerM, headerMe, headerJ, headerV, headerS, headerD],
    jour,
    mois,
    dt = new Date(value);


    // récupération du jour sélectionné (/mois)
    var jourMois = dt.getDate();
    // récupération de l'indice du jour dans la semaine
    var jourSemaine = dt.getDay();
    // création d'une date commençant au lundi de la semaine
    if(jourSemaine === 0 || jourSemaine === '0') {
        jour = jourMois - 7;
    } else {
        jour = jourMois - jourSemaine + 1;
    }
    // affectation des dates aux headers
    for(var i = 0; i < 7; i++) {
        var m = 1;
        var d = jour + i;
        if(dt.getMonth() === 1 || dt.getMonth() === '1') {
            if(dt.isLeapYear() && d > 29) {
                d = d - 29;
                m = 2;
            } else {
                if(d > 28) {
                    d = d - 28;
                    m = 2;
                }
             }
        } else {
            if((dt.getMonth() === 3 || dt.getMonth() === '3' || dt.getMonth() === 5 || dt.getMonth() === '5' || dt.getMonth() === 8 || dt.getMonth() === '8' || dt.getMonth() === 10 || dt.getMonth() === '10') && d > 30) {
                d = d - 30;
                m = 2;
            } else {
                if(d > 31) {
                    d = d - 31;
                    m = 2;
                }
            }
        }
        if(dt.getMonth() + m > 12) {
            mois = '01';
        } else {
            mois = (((dt.getMonth() + m) < 10) ? ('0' + (dt.getMonth() + m)) : (dt.getMonth() + m));
        }
        head[i].setText(head[i].text.split(' ')[0] + ' ' + d + '/' + mois);
    }
    
    
    Ext.ComponentQuery.query('gridpanel[itemId="grid"]')[0].store.filterBy(function(record) {
        var date = record.get('date').split('/');
        var semaine = new Date(date[2], (parseInt(date[1]) - 1), date[0]);
        semaine = Ext.Date.format(semaine, 'W');
        var s = field.getRawValue().split('/')[0];
        if(semaine === s) return true;
    });
}

The previous one works fine on every call I do, except for the button one.
Here's the beforerender event I use on the datefield, which also calls the function above :

onDatefieldBeforerender: function(abstractcomponent, options) {
    abstractcomponent.setValue(new Date());
    abstractcomponent.fireEvent('select', abstractcomponent, abstractcomponent.getValue());
}

Hope you'll understand why it doesn't work especially for the button... Thanks in advance.

[EDIT]

Moreover, it totally blocks me on my work as it is the last point I must get to-work before I can change of subject... So please, help me.

What do you mean by "but for the button one" which is what I read doesn't work correct?

[sencha-dev2]

Forgive me, I haven't been clear, I meant that every call I make to the function from the button click event doesn't work. Every other call from any other source works well...
